Hi,
I am a noob too, starting to play with opengl using the redbook and
factor so here is an example of how to make an animation using timers.
I couldn't figure out how to do it using <slate>. It is probably not
the best solution and it flicks (I still don't know how to do
double-buffering in factor).
Hope its usefull.
