Hyperspaces is a promising looking add-on to Apple’s Spaces feature in Leopard. It’s in a private beta at the moment, but I’ll be keeping an eye on things. I’ll leave you with a quote from the website seen as how it’s the best description you’ll get.

Hyperspaces is the ultimate way to customise your spaces. Customise each and every space the way you want using colors, desktop pictures, text labels and even the name of each space!
