We call recursion the fact of allowing a function to call itself until some condition is met. It is really useful when you're doing complicated math calculations AND when you're trying to draw repetitive patters in Flash. Now I know you guys would love to hear about the math, but life's unfair, I'll only talk about the Flash.
All right, so a recursive function is a function that does stuff, and then calls itself, possibly with a different set of parameter, until we tell it to stop. To illust
