This is my first submission to NG. It's not terribly cool, but it's nifty. I hope you enjoy it.
How it came to be:
Well, I thought: what if I animated an object? What if I animated the animation of that object? What if .... well, you get the idea.
So I animated a rotating ball. Then two. Then four. And I said to myself: "Hey. Powers of two!"
And that's how this animation came into being.
