Well, mine isn't nearly as pretty as the ones on the Colourlovers blog, but
Here's my first attempt using Apophysis 2.02(download is free, guys!)
This is a really nifty tool. The fact that the output is in .jpgs means that it will be easy to incorporate these "flames" into other images without trouble.
I say, find yourself a copy of this and play with it-- then post your results so the rest of us can see them!
