Yep, thermochromatic stuff is what you want to look into, but I've found unless you're looking for novelty cups and all, its pretty hard to find this stuff. I was once working on a project at the local nanotech institute involving knotted regions of carbon nanotube yarns and thermochromic dyes for flexible, inter-woven displays. Trying to locate suitable dyes was probably the hardest part (well, besides the fact that the concept was fundamentally flawed )

I know they make mouse pads out of it. It might not be as big as what you are looking for but...

Search for heat sensitive mouse pad on google for more of them.
