The performance characteristics of having both open at the same time are bit cute. In my case (Firefox/Win7 on some random laptop) the WebGL one renders a burst of frames, then pauses for a sec, and then another burst and cycle continues.
I misread this as "meatballs". Needless to say, this was not what I was expecting ;-). I like the effect. I wonder what meta-metaballs would look like...
I was wondering a while ago if you could use an effect like this to get reasonable performance for real-time raytracing. It wouldn't be realistic, but you might get a nice painterly look with fancy lighting for 3d scenes.
