Try the Raspberry PIXEL Platform on Your Desktop

PIXEL stands for Pi Improved Xwindows Environment, Lightweight. On the desktop, PIXEL is only available as a live image, but for anyone without one of the Raspberry Pi boards, wanting to experience the new Pi environment on, this is definitely worth carrying around on a bootable USB flash drive. Why? Not only are you getting a full-blown, Pi-flavored desktop operating system, you will also find some interesting programming tools installed by default.
