Very cool article. Providing actual working demos for each step makes the technique a lot easier to explain to others.

I had fun implementing this effect a long time, in a pre-graphics-shader era [1].

Honestly, I haven't even read it because I'm tired and I'll leave it for tomorrow, but this is the reason I check HN, I've gotten good enough at skimming through and article and the comments to know when an post is worth it and this looks awesome, not much of a point, just happy to see quality material in HN (not a rant, just happy to find a great post).
