Multi-touch table based on Krestianstvo SDK
Here is a video from the recent event, which was held in the "Museum of Science" (Russia, Vologda), where the Multi-touch table based on Krestianstvo SDK was shown. The table is controlled directly by Krestianstvo virtual space and it's objects shared on the Croquet island. So, several such tables could be organized into p2p network and become a really interactive classroom, programmable just in Smalltalk. For recognizing reacTIVision fiducial markers and TUIO protocol are used (based on Simon Holland TUIO for Squeak work). For music synthesising SuperCollider through OSC is connected, using the idea from SCIMP (SuperCollider Server client for Impromptu) and realized in Smalltalk.
