Very nice
I love watching these loops over and over and over and over and over and ... you get the point :) Both black and white and color versions are great!
Hope to see another similar collab in the future.
I was wondering about Flash "screen savers" but haven't really looked into it yet. I know, there is the fullScreen() thingy in Flash so if there's no sound option for screen savers then a simple .swf or .exe projector file might do the trick. That's how videos (e.g. youtube) work, so there has to be a way. I'm not sure about the scaling but that's probably just detail.
