I forget who..But someone here made a really cool looking rock scape out of that spray foam stuff..I'm not sure how it held up with time though..

Might I suggest a easy way to diffuse light on the back wall that a member showed me was to use that car window tint stuff on the outside of the tank,I have it on my 30g and it looks and holds up awesome..

Not sure if this is the thread you were thinking of but it's the first one that came to my mind.

"Great Stuff" is the easiest brand of foam to find. But it expands like crazy so keep that in mind when using it

I remember that someone had made some real nice arches with that stuff but didn't use enough crushed coral in it and it floated so make sure you use enough crushed coral, rubble etc. when your making your wall or it will become a raft in your tank.....
