It begs me to use the cliché thinking outside the box. I'd love it if you chimed in on benchmarking on this post : http://dispatchevent.org/mims/discussion-how-best-to-benchmark-flash/ Hey Doug,

I'd be keen to see how the new vector class performs against the array. it's the same only its restricted to one datatype so it's supposed to be more efficient. Presumably this is one of the reasons bytearray and bitmapdata are quicker. Don't give up on the bitmaps, there are some very low-level operations there that can't be quickly emulated any other way. Here's an example using three different filters to emulate cellular automata: http://www.5etdemi.com/blog/archives/2005/12/flash-8-experiment-the-game-of-life-and-cellular-automata-using-convolutionfilter/ Interesting couple of articles.
