The Framework for TUIO-based tangible computing with SuperCollider now is called SETO â€“ SuperCollider Environment for Tangible Objects.
You may install it in SuperCollider by evaluating
Quarks.install("TUIO") // still the old name...
and then restarting the interpreter.
If you have a GUI app (Cocoa or SwingOSC atm.) you may want to use TUIOServer:gui to see the recognized objects and their states.
More information can be found at the SETO home and the TUIO home.
Have fun and feel free to contact me if something isn’t working right.
