[PD] GEM and video synthesis

[Paris Treantafeles]

hello all,

i'm very new to pd and gem.
i've gone through a gem tutorial and get the idea of some of what can 
be done with respect to manipulating images, movie clips, and 3d.
what i'm wondering is about is using gem to create patches closer to 
analog video synthesis.
a friend and i work on this type of equipment, analog signal 
generators, pulse generators, etc. and create video images on tv 
screens.
i'm curious to find a software solution and wondering if gem is the way 
to go.

if anyone has some experience with this, i would appreciate any links 
to info or patches.

thanks,
paris
