In 2009 vade and I developed the VVFFGL framework which provides FreeFrame GL support for VDMX. Vidvox have open-sourced our work: as well as the framework there’s a Quartz Composer plugin for running FreeFrame GL (and older FreeFrame 1.0) plugins in Quartz Composer.

vade and I have just released Syphon for realtime video sharing between apps. Read about it at createdigitalmotion. Udart at Obscura did a nice post about Syphon too.

I won’t make it to GLI.TC/H in person, but I’m there in spirit in Bob Weisz & Paul Korz’s installation at the gallery, and I’ll be making a long-armed remote-control appearance at vade’s Realtime Glitching workshop on the Saturday.

Addendum: Nice writeup by Tom McCormack at http://rhizome.org/editorial/3819

A plugin for Quartz Composer to misrepresent pixel-buffer data on the GPU.
