Correct me if I'm wrong, but I'm beginning to think the goldfish aquarium ...ummm GF - is a prototype of the future 3D background SereneScreen Marine Aquarium (3DMA?). Seems all the tools are there - the 3d swim space - the physics, AI, collision avoidance, etc. ... like a 'warm up' version - simple - but with lots of muscle behind it. Enter, Jim - the artist - to add skin and *POOF* - 3DMA!
...now, what button do I push to make that happen?
I know, I"m bad at over-simplifying things sometimes.
