Following up on the previous post I am now putting the demo app up for download. It is slightly modified from what the screenshots show - it now only has three rotating cubes, each rendered using a different technique. From left to right they are using: a Normal Map, a Height Map, and a Gradient Map.

You can download the demo here. I make no guarantees that running this app won't turn your computer into a black hole, ruin your day, or any other bad thing you might think of. That said, I have only tested the demo on two computers so far and so would love for you to contact me if you encounter any problems. The demo requires DX10 but shouldn't be too performance intensive - I get around 600-700 fps on my laptop (equipped with a GeForce 9600M GS).
