I think this version doesn't use the "Memory" API. I have two versions, one that uses it and one that doesn't and the difference is very minimal - not worth to drop the Flash 9 support at least. I'm not sure if RF2 can be done in regular JavaScript though. Maybe in Chrome 3, which about twice as fast in my 3D canvas benchmark test (this one: http://gimme.badsectoracula.com/canvas3dbenchtest.html http://gimme.badsectoracula.com/canvas3dbenchtest.html ). But Flash works 'equally' in almost all browsers while JS+Canvas is very browser specific when it comes to performance.
