Check out the tiny Raspberry Pi computer set up and running Quake III Arena. Now that the little machine is being delivered to customers after the delay, we can see exactly what this thing is capable of doing. It is like getting the Sinclair ZX81 all over again, but without using a black and white TV for a monitor!
This looks like the beginning of something on a larger scale as the YouTube user RaspberryPiTutorials says;
I plan to provide Linux tutorials for those who are new to it, configuration tutorials once the Raspberry Pi is out, and programming tutorials following that.
