Ok, I added some more details, changed the color of the goo (it's more 
a gas than goo now, I think) and tilted the camera a bit. This image 
took nearly two days to render, mostly because there are over 5000 
objects in the scene, each of them is either a media container or is a 
reflective surface with a normal. The rest of the rendering time is of 
course due to radiosity and focal blur.

I know that the segments of the flexible tubes (should be the right term 
for it, according to dict.leo.org) at the top look wrong, but I was too 
lazy to get it right. Maybe in the next image...

Please share with us what may be wrong with the segments....

It looks really cool.. except for that spotlight on the floor. That, and 
the fact that the brightly-glowing gas doesn't appear to actually 
illuminate anything.

I'm sure that adding decent-quality radiosity would make the render time 
obscene, but perhaps the floor could be changed to look interesting?

Some of the JPEG artifacts looks really bad. This image really deserves a 
PNG version!

Clearly it *was* worth it...

I didn't rate the first one all that much, but this is way cooler.

Andrew.

I could go into a lot of detail now, but basically the problem is this: 
When placing objects along a spline by evenly subdividing the time 
range, you don't get evenly placed objects in general. You would either 
have to "warp" the time parameter to take that into account (doing so 
exactly involves a ton of nasty math), or to do something like what Rune 
did in his spline neck macro (I could have used that, but didn't find it 
on my hard-disk anymore).
