I tested out LuxRender

There's a bunch of noise all over it, the model sort of sucks, but it's pretty cool I guess

I tried to get LuxRender to work in Blender 2.5 with the tutorial at Blender Cookie, it didn't really work out so I used it in 2.49.  I'm pretty sure the results would be the same.  I have to figure out how to get rid of the sparklies everywhere, I left this thing running for 6 hours and they still weren't gone.  It might be because of lack of light, but I think I put enough light in.  Right now I'm trying hard to get external renderer to work for me, I've seen a lot of amazing stuff at the Blender Artists that was rendered in Yafaray and Luxrender.

Edit:  This is a new version
