Explosions!

I finally found a really good looking explosion made in blender. Here's a link: http://blenderartists.org/forum/showthread.php?230329-How-to-make-a-very-realistic-fire-explosion-in-Blender-2-5!
The only downside is that I can only get it to work on older versions of blender. Right now I'm using 2.62. I tried it in 2.65, but couldn't find the options I needed.

I have it baking now, if it looks good I'll post a result soon!
