I scored one of the only copies of Windows 7 Touch Pack out in the wild, and it really blew my mind, bringing the full power of Microsoft Surface to touch-enabled Win 7 PCs. Have a look:
Microsoft's expanding Windows 7's multitouch powers with the Touch Pack for Windows 7, a pretty sweet collection of multitouch apps. Three are Surface apps, like the Virtual Earth 3D Surface Globe (guess what it does?) and Surface Collage. The other three are awesome-looking games.
