First off, you need FLASH 5 for this -- version 4 won't do. And yes, there are some things that could be smoother here; this is meant to be just a quick test and experiment here, not to be some fascinating finished item. The buttons don't need to keep flashing, and I could have a range of acceleration buttons, sort of a roll-over slider. And no, there's no reason for the window to be that small. I just had to slam this together quickly. I'm supposed to be packing -- I'm moving later this week!
