I have been looking to create custom errors for one of my web servers. Inspired by some of the CSS3 font research I have been doing, I decided to build a graphic error page without using any images (with the exception of the Husky Ninja logo). I have checked the work in all modern desktop browsers and it seems to hold up just fine (although it isn't that mobile-phone friendly). You can play with the finished version here.
