The Learning Everywhere project at The Concord Consortium was an open-ended project to try and play with new ways students can interact with science both out of schools and in museums. I made an electrical grid model based on a giant smart-screen table, with little physical model windmills and powerplants the user could move around; made a mobile app; collaborated on designing a card game (also based on the electrical grid); and experimented with mixed-reality projections.
The last of these required me to learn computer vision technologies, and to recall lots of dusty geometry for all the alignment and keystoning and stuff that was required. The video at the bottom is a demo of it in early stages, paired with our Energy2D simulation, which can model heat flow through air and materials.
