Just wanted to point out not working on Chromebook Uncaught Error: This demo requires the OES_texture_float extension I've seen this before though on Reddit, pretty cool how well it works on Mobile. Also I realize OP may not be related to the post/created it and I should file a bug or whatever, I'm just posting it here.
