Temple of Zoom
Temple of Zoom is a great platformer that manages to use the features of the product it promotes (the Panasonic Lumix TZ3 digital camera) as integral elements of the game rather than as tacked-on graphics and splash advertisements. The shutter is the exit to each level, the zoom lens is a rising platform, and the hot lava is... well, I guess the hot lava doesn't come from the camera, does it?
