It's very cool up until everything starts going a bit see through - although it does still look good even then.
Funny when I read the word "glitching" I assumed it would be a framerate hitch, which might be cause by GC, but I did a quick timeline grab and it seems OK for desktop. Collects about 12MB every 10-12 seconds. That might have more of an impact on mobile of course, especially Android.
I'm having that kind of issue with a game I'm working on - in my case I'm being way too cowboy about creating and throwing away JS objects for particles (only in 2D on a canvas) and it's causing GC framerate glitches on Android.
From what I've experienced and read about, it seems the best approach is not to create/destroy objects at run time since it can be an expensive operation and cause frame rate issues. It's better to hide them and build as many as you can when the app is started up.
