Last summer, I spent a week or so hacking together an entirely new interface for Odeo. We called it /play or "playjax" for fun (cuz it's all Ajaxy and stuff).
It was built with the idea of what if Odeo was a connected web-based media player, instead of a directory of content? Since then the real Odeo site has changed a little more in that direction, and we stopped pointing to /play, because it was confusing to have two interfaces.
But I was just poking around on it and still really like the way it works and looks (thanks to Biz for the killer visual design).
So, there's that.
(BTW, more interesting Odeo news coming soon!)
