The ultimate explostion?

I was thinking about creating an explositon with the new tools from the Google summer of code. It would make use of both bullet phyisics and the new smoke simulator improvements. I was thinking of blowing up a bridge or building, although a car would be interesting. I’ve done a few experiments and had little luck so I thought that this could become a communtiy project. That means that people would pool tricks and ideas and a shared blend file to create this master fireball. If you are interested, find or make something to blow up.
Here is a little bridge that I threw togther:bridge2.blend (865 KB) (It would be nice if someone made somthing a little nicer and textured it)

For starters I found these nice files by miikah:http://www.miikahweb.com/en/blog/2012/08/10/blender-fire-testing---blend-files

-Thanks, hope to see some results soon.

P.S. you will need 2.65 for these files to work.
