I've only seen video feedback done in analog. Take a camera, hook it to a TV, so the TV shows what you're filming, and then film the TV screen. I would guess that the delays on processing digital data on a computer would make it impossible to do on a computer, but I may be very, very wrong. Try hooking any object's output to its input and you've essentially got a feedback loop. I don't think you can do this in GEM though.

I didn't saw that graphic... but i'm very interested in this kind of "visual feedback" patches too. So if someone has more info about this, it would be cool to know how to do that.

if anyone had a patch that could show what this technique means. Its kinda like a shadow of an object remains as it moves through the space. Thanks nicky
