I did an animated 3d plasma for js1k some time ago. It's not fast but it's animated: http://js1k.com/2013-spring/demo/1412

h key toggles the height map.

It uses a simplified version of the MagicEye.js algorithm which generates horizontally repeating patterns for hard height changes in the source image. That's why I went with a plasma in the end.
