It’s happened to all of us. You’re poking around the web, and follow a link to a different site, and — WHAM! 404 Not Found. Some are plain, usually generated by the server, but some companies and sites take it to the next level and turn the plain 404 Not Found page into an experience all itself. Some are humourous, some are informative, and some are just great design. But the folks at Woltbit.com have compiled a list of cool and creative 404 pages. Pay attention to #2. Blue Fountain Media has turned their 404 page into a playable Pac Man maze!
