OT: Halloween windowed graphics?

["big_red_frog" <atod@xxxxxxx>]

Hi All,

Almost on topic

While setting up my projector, I noticed that in the dark of night I
can project very vivid images onto the first floor window, which has
a translucent blind, giving an excellent result from the outside.

So for halloween, I though it would be good to project a suitably
halloween themed moving graphic in that area.

This only takes up about the middle third of my projection screen, so
something like the nvidia wolfman demo, although seeming well suited
is not, unless I can figure a way to make it run in a window, which I
can size and reposition.

So does anyone out there know of a decent windowed 3d demo, that I
can position on my desktop, or of an easy way to get a video loop in
the middle third of my screen...
