I record a tutorial for Processing and Syphon, an OSX technology that allows you to share videoframes between applications.
This tutorial is for Processing 2.0, but it can work on Processing 1.5 with additional code (ask me if needed).
Thanx to Vade & Bangnoise from Syphon, and Andres Colubri (for its Processing implementation).
