I just backed my first project on Kickstarter, Playsurface:
We have a new mechanical and electronic design approach to bring large-format touch computing and home touch tables within reach of ordinary developers and consumers. Our development of Playsurface started by assembling the best open-source optical touch table plans available, and we intend to create a hackable, multi-use, blazingly fast touch computing platform for gaming, music, browsing, device control, and other applications. The goal is to enable cutting-edge performance at a price point that makes buying a touch table similar to many consumer home computer purchases.
Giant multi-touch DJ controller here I come.
