Interactive Sliding Data Visualizer.
This was definitely one of my favorite projects I have worked on in a long time. Starting from scratch with such a full-scale project really sharpened my skills as an engineer - as we had to tackle challenges in the software, mechanical and electrical intricacies, as well as the overall aesthetics of the project. Our final project made its debut at a special gathering in the Packard Electrical Engineering building on Stanford's campus before it made its way to the Exploratorium in San Francisco with intention of being used for youth education.
