Description	NEWER VERSION: http://www.youtube.com/watch?v=5A9Eh6D-K_g This is the awesome Bad Apple shadow art video (based on the Touhou games), traced in realtime and projected using my laser scanner :) Last night at 6am I was bored and copied and pasted some libavcodec example code into my laser framework, and hooked it up to the tracer I used for the metaballs and fire effects on my LASE demo. It worked a lot better than I expected it to! This is a slightly refined version with a few tweaks to the algorithm, but it's still pretty naive. Edit: more info at http://openlase.org. Recent versions of the software work a lot better and blink a lot less, and also support real edge detection for videos that aren't just blank and white ;) Original video (and input to the realtime tracer): http://www.youtube.com/watch?v=UkgK8eUdpAo
