Thanks for responding. I understand the difficult position you're in with the limited technology of Java. Settings for the lighting would be great, as I'm sure many people will likely have PCs with tempermental lighting. FYI: I have a Radeon 5770 graphics card (with settings that I have meticulously customized for gaming) and a Samsung monitor. 

Just a note: it's not a really Java thing. I can do anything OpenGL can do since it's the thing doing the rendering. The lighting and colors would look exactly the same in any other language because they were painstakingly tweaked by me to look exactly the way they look.

I obsess over these things. I spent 4-6 hours just getting the flame colors so that they looked right both near and far. I have about 20 side-by-side test shots at various times of day just for the tweaking of the flame colors.
...don't even get me started on the ambient sounds.

I totally respect that. Those are nice flames, btw. I was quite impressed by them.
