Oleg, Ian may be stuck in motel bathroom memories, but I have a different problem; I think I have been hypnotized staring at the animation for too long, so consider my comments in that light.
Your animation does behave nicely regarding the window management on my Mac. I can use the .ijx window and resize the isi window. (I noticed that you removed reset and glpaint from your code, too. And I am not sure if that did anything or not.) There is a little quirkiness of your animation that I do not notice with Dan's. Every ~17 steps of the animation there is a stutter step. Somebody please snap your fingers to release me now.
