Peter Kirn has a great overview of how Chris O’Shea is going open source with his experiments in building tangible interfaces — interactive tables on which moving physical objects (like blocks) create visuals and sound. One obstacle in this technology has been people haven’t been able to refine the techniques; they just create bare-bones proof-of-concept but haven’t been able to build on others’ work. This is really encouraging. Link.
