While I realise that this request is years old at this point, I'd love to throw my support behind it. Vuo would be a spectacular way to bring visual art to iOS devices and all the weird interactions (tilt, multitouch, orientation, location, camera, audio) that they offer.
This is really fun. I'm planning to use this to create a simple art project for a local bar, where people can walk up to a laptop with a camera, and their face is replaced with an image. I've got a working prototype based on the sample rectangles code, but have hit a roadblock as the "Process List" node doesn't give an index, and so I can't figure out how to easily use a different image for face 1, face 2, face 3 etc. Is there an easy way to do this?
