Build: Multi Touch Surface

I haven't been posting much since I've sort of started my exams today, but I will try my best to keep it up to date. I recently found this very interesting build for a multi-touch surface that seems pretty cool. It use internal refraction to work and the disturbance when it is touched. Very interesting build and even has a pretty cool video to show it off. The link can be found here. I've also added the video here if your interested to watch it.
