Memo, of the rather splendidly-named Mega Super Awesome Visuals Company has very kindly setup an archive of qcFX compositions (Vidvox’s name for Quartz Composer compositions designed to work as realtime video effects within their VDMX5 application).
Lots of people have registered, so hopefully we’ll see the archive expanding in the near future, especially as people start to fiddle with the exciting now tools that came with the Leopard version of Quartz Composer (v3.0).
The archive is here. My efforts are the ones prefixed with ‘tb’.
There’s also a selection of qcFX on the VDMX Quartz Composer Wiki.
