A little something I started playing with last night and soon found myself up half the night turning it into an application.

This is all bitmapdata, not a single vector, so it’s pretty speedy. Still, it’ll start choking if you get too complex. I’m not sure where it’s heading, but my mind is filled with features to add to it, all of which will go in pretty easily. My general train of thought is to have this as an authoring swf, and allow people to save out their drawings, and play them in a separate player swf, which they could put on thier own site.
At any rate, it’s pretty fun. I’ll probably port it over to AS3 eventually and see what kind of performance that gives.
