5K

The 5k contest was conceived of by Stewart Butterfield in the fall of 1999 and the first competition was launched in early 2000. It is now run by Stewart and Eric Costello. (You may contact them using this form.) The design for the 2002 site was created by Caterina Fake. You'll note that it only uses black and white pixels ("look Mom, no gray!")
