Thank you for your interest. What browser do you use? It seems to work better on Safari on my MBA.
Also, as stated on my GitHub page I used primitive [1] for the lions example. What svgasm adds to primitive and other tracer tools is the ability to process a GIF (or a sequence of images) and make an SVG animation out of the sequence.
Do you mean recompiling primitive or svgasm to JavaScript? No, it is not currently possible.
But yea it would be cool to have a web version of svgasm that uses some Javascript raster image tracers out there. I will be working on it and posting to HN later to anyone who's interested.
