Well, I was inspired by Scott McDonald's lava lamp pictures, so I
decided to try my hand at creating one. The lava blobs still don't look
quite right and I still need to work on them. I've been playing with
ambient and diffuse values pretty much all day. I'm still not quite
pleased with the glass and the water either. But anyway, tell me what
you think, comments, suggestions, etc.

damn. thats all i can say. damn. this is going to look great when
you're done.
i'm semi-done with my lavalamp, on to experimenting with some stuff and
doodling with the raytracer right now. if what i'm tracing now ends up
looking like i want i'll post it later tonight.
i need a faster machine soon.

I think the blob look really good! Although the bright parts look a bit like
they are a reflection (are they?) and not only being lit up by the lamp. But
they look very realistic with their coloring that suggests different
thickness and density. I also would make the lamp a bit brighter (the
outside light is more prominent than the light in the lamp.)
BTW, you might want to check your system time: You message is posted with
1/1/98 which makes it show up at the wrong end of the message list :-)

You're right. The bright parts are a reflection, but the only problem is getting
rid of them. The blobs have no phong value, so there shouldn't be any specular
reflection, so that leaves the "water" inside the lamp. But when I set the phong
value of the water to 0, the reflection was still there. I'm gonna try and
rethink inside of the lamp. Thanks for the encouragement.

I don't really see any problem myself. Looks nice, I like the "foiled"
metal a lot.
I thought the problem mentioned was the old light-bleed-through that
blobs used to do (now? Seems that was fixed in 3.1*) and triangles, etc.
still do.
I don't see that here, if anything looks almost like you have a photon
map faking the light bounce off the inner glass surface. You don't do
you? ;}
