404 error pages - an often overlooked page of your website

When I recently surfed the web I encountered a 404 error  as it quite often happens. But to my astonishment this page was really well designed. After seeing that one I got a bit addicted and every time I visit a website now, I check their 404 error page - with more or less pleasant results.

And as we at Mako are currently re-developing our own website it is something we're thinking about now as well.
Below are some of the prime examples so far (and believe me, I've got loads more).

"This page has been kidnapped!"

"To free this page please click here!"

So let's see what we come up with. We'll keep you posted...
