This composition shows a way of using the interaction patch and kineme's spooky to manipulate the vertices/uv's of a mesh. I thought it might be a handy, non-obvious kind of setup to check out. Since my initial publishing of this, spooky has also become more stable / less leaky.
Since this, I've developed some higher-rez approaches by totally avoiding the iterator/spooky, but this has a certain immediacy and some aspects that I like. I also enjoy that it shows how info from a consumer iterator can be broadcast outside of said patch.
