404 pages don't have to be boring

In a fit of desperation, I created a list of files that I seem to always forget to work on when I'm building a website. The 404 page or "not found" is one I nearly always forget. It's not surprising that I do, as after all, the page only shows up when a link is broken - and I don't generally post broken links on a new website. But when I do remember to design the 404 page, I try to design one that is interesting, useful, and fun for my customers, like the ones found on Dzine Blog.

How would you finish this sentence - The elements of a great 404 page include... I would include:

• links to help
• contact information
• search
• suggestions for possible corrections
• something fun, so the customer isn't annoyed that the link is broken

What would you include?

Have you created a great 404 page? What do you like best about it? The nice thing about 404 pages is that they make great portfolio projects because they can show your programming and design skills, and they're only one page.
