Our computers use the colors RGB (Red-Green-Blue) in a mix to show you all the colors you see on your screen today. In total a computer can show you 16777216 different colors.
A colleague of mine took this fact and created a website dedicated to using all these colors in a single image, only once. His website is allRGB and it is getting quite some blog coverage if I might believe Google. He even had some coverage on a German web-tv show.
Off course I was amongst the people to submit. Having little time I created and rendered an pseudo random image during lunch at the office. You can find it here. I also took the liberty of submitting some links to reddit and stumbleupon. Just for kicks.
However, other people like ACJ himself have put a lot of time and work in their creations. See some examples and consider trying it yourself as well!
