Here's a very cool 3D test model that was prepared for the Galaxy Tab:

Beautiful use of geometry and post processing effects. I'd love to see this in a game, so here hopes the developer has something else in store.

The Tab has really impressive graphics performance (PVR SGX540), and I assume that the majority of this is being processed in-gpu (I should hope anyway).

Masterfully done.
