The sketch-camera thing is turing out to be trickier than I thought. One issue is resolution. The mac's web cam is 640x480, and still frames appear a bit blurred. I'd like my sketches to be crisp.

One solution I'm considering is "super resolution" — overlaying multiple still frames of video on top of each other. This requires aligning the frames, which I'm concerned might be slow in JavaScript.

I'm curious what the mac does with it's "signature thing".. does it use multiple still frames? maybe I should try showing it some image that is pretty detailed, and see how it does.. hm.. the answer appears to be "no". I drew a dotted line with about 6 dots, and it turned that into maybe 3 dots..
