Stopdesign.com is a very clean website to look at, and a breeze to find information on. The company was founded by Douglas Bowman in 1998. Another interesting thing to mention; Douglas is the Creative Director of Twitter.

He is using images and icons to give you an impression of the software he uses, and to show the visitor his recent artwork. The page is divided in four main categories with their own colorized style and layout. A simple and very effective website!
