Syphon is an OS X specific tech to allow applications to share frames. This allows a VJ to drive the sculpture using industry standard apps like Resolume.

Hey Fragmede - if we turn on the Config, it won't launch. "library not properly installed". That's probably OK but can you put something in some readme about how it's supposed to work? And a warning in the Config section that it's not supposed to work with checked in code? Or check in a library? Otherwise it's a bit of a time bomb for the unwary....
