Hi Stuart,
This patch is not mine (do not remember), but can help you.

Re: Trail effect

Sounds like feedback is what you're after there. You could do worse than investigating the Core Image Accumulator patch.

I've attached a basic example.

Incidentally, I'm a big fan of your work, especially the 3D stuff (bit of an 'thing' of mine, in fact)! Good to see you here, Stuart.
