So, I was browsing some stuff about a week ago, and I found this, can't remember where I found it, but it's a cool utility that lets you make your own flame fractals.

You can do some pretty sick stuff with this, and it's easy to learn, too.
Example of what you can do: (Huge images)
I know there's a lot going on in that one, but I just discovered a couple functions right then, hehe.
EDIT: Dangit. Images broke. I guess I'll upload them to imageshack tomorrow.
