Hey!
Just wanted to share a little test I did for fun. Sorry for the crappy youtube quality, it looks much better in uncompressed HD.

It's basically a simple animation I did while testing and learning the “for each” sop. I guess it could also have been easy to do with copy sop as well.
Comp and finaling also done in Houdini! Enjoy!
