Sliding glass doors for Varanids?

[crocdoc]

The fibreglass one was for a semi-aquatic animal, so it was an entirely different scenario. I didn't go for realistic rocks and wouldn't have known how at the time, but that's not a restriction of the fibreglass vs polyurethane elastomer.

If I recall correctly, I built a wooden shelf (which would end up being the basking area) and then used wire mesh for armature to shape the area that would slope away into a pool. I coated the lot in polyester (pigmented) soaked fibreglass matting and then did a pigmented layer with sand and rock mixed in for the 'rocky' surface.
