I have been very curious to get my hands on the new Syphon technology.
So I tested the demos to see if it could be made to work in Modul8. Unfortunately not at this point
There are simple explanations for this as the Quartz Composer implementation in Modul8 has some limitations. It only allows 'safe mode' patches and the Syphon plug in does not work in safe mode.
Also in theory the FreeFrame plug in could work in Modul8, but Modul8 only supports FreeFrame 1.0 and the Syphon FreeFrame implementation is FreeFrame GL 1.5
However I have hope as I saw Ilan Katin demoing the new MadMapper tool in an online screen cast, and I am sure I heard him say that he was using a modified version of Modul8 that runs Syphon. So let's hope it ends up in a new version of Modul8 soon.
