Windows Vista has some eye candy doesn’t it. The new alt+tab, the preview of windows on the task bar. But Ubuntu 6.10 with XGL & Kiba-Dock has just about all the features Vista does, and some which it doesn’t. You can use the middle mouse button on your desktop to spin a 3D cube, each side of the cube contains one of your desktops. This isn’t static images either as it’s all real time. However, I’m not sure how much memory and CPU is used up.
