Hello,
Want to share an experiment doing with Croquet and Krestianstvo SDK: a Multi-touch table. The table is controlled directly by Krestianstvo virtual space and it's objects, being 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 objects 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 being realized in Smalltalk. Video of the table in action: http://vimeo.com/18211323 Blog post: http://nsuslovi.blogspot.com/2010/12/multi-touch-table-based-on-krestianstvo...
Thanks and Happy new year! Nikolay Suslov
