The current Windows Azure Management Portal has a few “custom backgrounds” available if you get tired of the very light gray background…

I don’t know the history, whether it is a feature, an easter egg, something they did for design mocking, or what (I’ll ask around), but nevertheless…

If you double-click in the margins of the portal experience on either side, it will rotate through a few different choices. I’m a fan of #2 and #3 I think! What’s yours?

It loops once you hit the end. “The more you know”
