Creating rotational spritesheet from single image

If you want to code it yourself, try here http://flexdiary.blogspot.com/2009/12/riadventure-inspiration.html . Note I wouldn't do this with an actual image, because the pixels won't look exactly right as they're rotated. But if you want to rotate a vector, it's a good way to do it.

looks like the flixel library can do it
