Rafael continues his look at the various components of the Windows 7 Touch Feature Pack with a game called Rebound:

Next in the list of toys that Microsoft revealed in the new Touch Pack for Windows 7 is Rebound. Rebound, developed by Fuel Games (the peeps that brought us Tinker), is a simple pong-like game with additions such as electricity, spinning projectiles, futuristic sounds, and clumsy AI; the perfect time vampire. Gameplay consists of a player (or two) placing their fingers on a set of orbs to create an arc of energy, to act as a paddle. The arc's strength and ball stopping ability is dependent on the distance between the player’s orbs. That's the simple rundown.

On the technical side, Rebound is a native Win32 application, tying into the DirectX 9, DirectX10 and PhysX APIs. The latter is interesting because you may get a little physics processing boost if you’re using a fairly recent NVIDIA GPU (Geforce 8 or higher) or if you shelled out for and installed an AGEIA PhysX Accelerator. (If you have a PhysX card lying around collecting dust, send it to me!) With regards to shaders, things are a bit gray. It’s not clear which shader model the game requires but my guess is 2. Shader model 1 is for wimps and 3 is a bit bleeding, compared to today’s typical mass-produced consumer PC. Simply put, if your machine can’t do Aero proper (with transparency), you will have issues playing Rebound. You may be able to speed things up by throwing more memory at it with DOS/4GW, however.
