Eric (Yes the WYOU ERIC!) sent me this note:

as you may have heard (janet) I've cleaned up an extra large
fishtank that's 5'x2'x1'
found it near the station
so
thus far, I've just been playing with florescent dye
(lit by a bed of 5 5-foot-long blacklight tubes)
really bright, really cool - so I'm sitting on hours of this
stuff already

you gotta see - the idea now (for your deal - though the footage
I have would already be great for backgrounds, underwater fuel
leaks, etc.) is to sculpt some half tube passageways
- backgounds that we could put a model in front of - could cast
shadows, etc. (things that are hard to bluescreen)

could guide a model through the tank, while tracking the camera
from the side
(this would require a small model - maybe 6-10 inches long)

line or track >o

I----brace----I

t b I t I
a a I a I so the camera
would be linked to the model
n c model n camera & always right on
target in the shot
k k k <- the whole thing
could then be mounted on a line
t a n k b o t tom and dragged
slowly through the tank
a solid
track might be better...I have some of this

I also have a fair pile of drainage tubing (black corrugated
plastic of various widths) that could make some good tunnels, maybe
some models of tunnel joints/secret passageways
and, of course, reactor cores.

Thought the more toxic-looking stuff in the sewers, the better -
as well as skeletons of enormous crocodiles and the like.

I'll try to be paying attention to my email - put EFFECTS! or
WAKE UP ERIC! in the subject line.
