thanks, but the kudos should go to Jakob for that.

That should not be.
Can't test it at the moment because Gem is stuck with the beachball (OS X) when i try to access the webcam now. Very strange I didn't update or anything.. Even reboot didn't help (?!) If that stays like that I'll start another thread about it.

Not yet. I'd like to extend the "Bewegungsmelder" patches with OpenCV examples, but at the moment i feel it is still not fail proof. I'd like to see pd-opencv as a package in debian/ubuntu/mint and also inside Pd-extended. At the moment those patches aim for being very distributable and only depend on Pd + gem.

I'll give it a try some time when i am at a Ubuntu machine. thanks!
