Stitching Up Success: A Recap of the IQ Center’s Inaugural Sewing Workshop

Learn to Sew a Tote Bag! Tuesday, September 19, 2023.What happens when you combine a state-of-the-art space, enthusiastic students, and sewing machines? Pure magic!

Last week, 17 W&L students came to the IQ Center with curiosity, excitement, and a penchant for crafting—ready to transform squares of fabric into tote bags. The buzz was palpable, the energy infectious.

And let’s be honest, who wouldn’t be excited? 

Setting the Stage for Creativity

Hosted by the Academic Technologies team, the night was designed to be an immersive experience. Taking place in Science Addition 202A, the room was divided into four bustling workstations.

Each station was equipped with cutting-edge sewing machines, including the latest addition to our tech lineup—the Singer 4452 Heavy Duty electronic sewing machine, fabric shears, heat-erasable pens for fabric, rulers, and sewing pins, lots and lots of sewing pins!

Academic Technologists Julie Knudson, Dave Pfaff, Mickie Brown, and Helen MacDermott, walked around the room to answer questions and offer tips as students worked. And yes, for the curious minds and eager hands, there were pre-cut 18″ x 18″ fabric squares in a variety of fun prints and colors and pre-threaded machines—because, at the IQ Center, we believe in eliminating barriers to innovation. Most of the fabric came through donations from the W&L Theater costume shop! Fabric that once may have been curtains on a stage set were converted to market totes.

Imagine having a 3D instruction manual that you could touch, feel, and refer to. To provide a multi-dimensional learning experience, Julie created prototypes of each step, pinned to foam boards for reference. This approach elevated the traditional instruction method, providing students with a tangible guide to navigate the tasks that lay ahead.  

Individual foam boards with finished pieces from each step for reference The workshop was more than just a fun night; it was an incubator of versatile skills. Our students gained hands-on experience in cutting fabric, measuring, pinning, pressing, backtacking, and sewing straight seams. 

By the close of the workshop, a crescendo of pride filled the room. Every participant left with a tangible representation of their learning—a meticulously crafted tote bag. It was not just an accessory but a physical manifestation of applied knowledge, collaborative effort, and creative expression.

Final Stitches

This inaugural sewing workshop is a testament to the IQ Center’s commitment to fostering multidisciplinary skills and community engagement. It was a watershed moment for the IQ Center, reinforcing its role as a sanctuary for interdisciplinary innovation. And if the smiles and the stunning tote bags were any measure, we’re confident this is the start of something groundbreaking.

We’re just getting started, and we’re threaded up for greatness!

The Art of Waterjet Cutting

The IQ Center recently collaborated with Studio Art professor Sandy de Lissovoy on a sculpture project for his ARTS 232, Intermediate Sculpture, class.

Students in the class are learning metal sculpture techniques and the new waterjet cutter in the IQ Center provides interesting options for creating metal work. The waterjet cutter uses a computer controlled, high pressure stream of water mixed with abrasive powder to cut almost any material, including steel.

In this “Digital Shapes and Metal Work Sculpture” assignment, students were instructed to create a portion of their sculpture using the waterjet cutter. This portion of the project gave them the opportunity to learn Adobe Illustrator, which is used to create the intricate vector shapes to be cut.

The IQ Center provided training and troubleshooting for the students during the project making it easy to incorporate this element into a larger project.

Meet ProtoMAX, the latest addition to the IQ Center!

The laser cutter in the IQ Center has the capability to cut materials like plastic and thin wood, but we haven’t had the ability to create parts from more durable materials, such as metal … until now!

The addition of a new water jet cutter makes it possible to cut intricate parts from a variety of materials not previously possible.

The process is similar to that of the laser cutter. Parts are created in either CAD or vector drawing software like Illustrator. Those drawings are converted into paths that the high pressure water jet follows to cut your part.

The fine abrasives used in the process make a smooth, almost polished edge on the parts.

An aerial view to really put things in perspective!

In March, the IQ Center took to the skies to gather data for the Geology department.

Knowing that some students might not able to attend lab in person, Professor of Geology Chris Connors got some help from the IQ Center to create a photogrammetry model of the rocky outcroppings he was interested in, so students could view the formations from anywhere.

Photogrammetry can be a tricky process. Essentially, the goal is to visually identify common points between multiple photos, and using sophisticated software, stitch the photos together into a 3D model that lets us zoom, rotate, and examine areas of interest.

There’s a lot to consider when shooting for a photogrammetry project.

For one, the shoots can take several hours – enough time for the sun to travel a considerable distance in the sky, which changes light levels, shadow positions, and reflections. This means a cloudy day is ideal, but it can be difficult to plan trips around weather.

Another consideration is how the pictures should be taken. Due to the scale and location of the subject, this project necessitated using the IQ Center’s drone.

This means an extra set of challenges: safe takeoff, flight, and landing, watching battery life, and the multitasking involved with both piloting and taking pictures is a lot to focus on.

The tradeoff is that previously inaccessible shots are now within reach!

Inspiration from the IQ Center

Just because the IQ Center is located in the Science Building doesn’t mean it’s only mean for STEM projects.

One tool in particular has found remarkably broad use across many disciplines – the laser cutter.

The following recent projects highlight its uses in the area of print making.

The wood is then coated with ink and used to make a print. The laser cutter in the IQ Center can be used in place of the carving tools to remove wood more quickly and more precisely than traditional methods.

This semester in Leigh Ann Beavers’ printmaking class, the IQ Center is collaborating on such a project. Students will create designs either digitally or by scanning paper drawings. The edited graphics will be laser engraved in the IQ Center and printed in the print studio using the same techniques as hand carved wood blocks. This process allows students to create a greater number of woodblocks with more detail than would normally be possible in a semester.

A similar technique is used to create rubber stamps which can be used for a number of practical and class-related projects.

Recently, Janet Ikeda, associate professor of Japanese, inquired about printing on fabric. She was interested in creating a custom Japanese headband called a hachimaki as part of a Lunar New Year video performance. Using the laser cutter, we created a rubber stamp that was able to print directly on fabric and the result looked fabulous.

Regardless of your discipline, please contact Dave Pfaff with any creative technology needs.

Dance in the IQ Center

This past Fall, the The Integrative and Quantitative (IQ) Center collaborated with the Dance department on two interesting projects.

Since the fall recital, W&L Dancers Create, was going virtual, DANC 110 (University Dance) wanted to create a video to be used in the program. The class created an original music score and choreographed a dance that utilized outdoor spaces around campus.

They worked with the IQ Center to shoot and edit the dance using equipment from the Center, including video cameras and a drone. The entire piece was shot and edited in 4K resolution and the 5 minute final version was included as part of the Fall program:

Another dance class, DANC 223 (Intermediate Contemporary Dance), experimented with the IQ Center’s motion capture system.

This system allows dancers wearing a special suit covered with reflective markers to capture the full range of their motion to a computer system. This is the same technique used in movies and video games to capture realistic movements that can be transferred to computer generated characters.

The IQ Center motion capture system was set up in the dance studio and projected on the wall, so the dancers could see the capture data in real time. The recorded output was then applied to computer generated characters and rendered as video clips.

Here the four dancers in the class were inserted on a computer generated stage together performing a similar dance routine: 

We then did some experiments in the IQ Center applying some more abstract shapes to the motion capture data. We hope these experiments will inform future motion capture projects.

Experiments in Virtual Reality at W&L’s IQ Center

by Paul Low and David Pfaff

The Integrative and Quantitative (IQ) Center at W&L is a collaborative space where new technologies are made available to the entire campus – often before we know exactly how those technologies will be used. A recent example of this is virtual reality (VR). At W&L we’ve been experimenting with the technology for a couple years, starting with cell phone-based VR systems (like Google Cardboard) but in the past year, the price and quality of VR hardware has reached a point that has attracted a much wider audience, including retail consumers and small schools like ours and this year we upgraded to a dedicated VR headset, called the HTC Vive. These new VR headsets provide a compelling (and immersive) way to visualize and interact with content but there is very little educational content currently available, especially for higher education. This means that, for the time being, getting the most out of these systems requires either creating original content or adapting existing material to work in VR. Fortunately, when it comes to visualization, many of the workflows that we have developed over the past few years for generating and manipulating 3D content such as molecular modeling, 3D animation, motion capture, photogrammetry, geographic information systems, 360-degree photography and video, etc. translate well to VR platforms with a little work and a healthy respect for the current limitations of the hardware. Developing interactive scenes for VR takes a little more work and some specialized skills but the potential for creating educational tools that facilitate active and blended learning at all levels of education are virtually limitless.

Since we are so new to VR, most of our projects can be generously described as “ongoing”; nevertheless, this summer we had our first team of student VR developers – a group of incoming first year students participating in the month-long W&L Advanced Research Cohort (ARC) program. Their project involved capturing motion of themselves performing various exercises (running, yoga, etc.) then visualizing and analyzing the movement in VR. This fall, we developed our first VR “homework assignment” with Jill Leonard-Pingel for her “General Geology” (100-level) class, and most recently worked with a couple of teams from Gregg Whitworth’s “Molecular Mechanics of Life” class to create interactive scenes that require “player” input to complete complex biochemical reactions in VR. Our ongoing projects include faculty and students in the many STEM fields as well as dance, digital humanities, and theater. The video below shows some of our ongoing projects in VR (most demonstrated by Ashley Ooms ’17), in addition to those mentioned above:

  • Examples of interactive structural biology models (catalyzed phosphorylation reaction)
  • Photogrammetry model of the Liberty Hall Ruins (on the W&L campus) and a laser scan model of a Wooley Mammoth downloaded from the Smithsonian both viewed at 1:1 scale
  • Viewing crystal structures in 3D (from the virtual homework assignment mentioned earlier)
  • Interactive scene developed for a group project in an upper-level biology class (Molecular Mechanics of Life)
  • A 1:1 scale version of downtown Lexington, VA in 1867 created in Sketch-Up by former VMI French Professor Ed Dooley
  • “Grabbable” MRI scans of the brain from the “Glass Brain” project
  • Motion capture animation from a dance class taught by Jenny Davies.
