Beautiful!! I've just ran it. The sample capx looks wicked! I imagined the hulk on rampage! CPU went up but i guess it was fairly reasonable. It dropped down as soon as it cleared its path.
Anyhow, I think this should be one of the default behaviors built into C2 along with R0J0hound's Canvas.
Speaking of canvases, do you think you could also look into Pode's SVG Canvas Plugin? Or perhaps come up with a better SVG support? Cheers!
