I didn't have time to even think about this when the thread was first posted but yesterday I was bored and started thinking about it and came up with something that doesn't have a single image.

It's not all that tbh and it's also not practical as it only works in FireFox and if you don't have the Trebuchet MS font it will also probably break, but all the same I offer this as an example/foundation of what can be achieved with XHTML/CSS without the use of images.
