PrimeTime rewind is an interesting way to mash up video content from the content creators like CBS, NBC, ABC, Fox, USA, Bravo, CW. The 3D cube can be spun horizontally and verticaly. Right/Left motion lets you select the content owner and a spin up/down lets you switch between categories (comedy, action, etc).
The site ultimately places your browser on an external site, so in the case of NBC and Fox content - you end up on Hulu. You will find the interface an interesting approach to visual content browsing.
Thanks for the tip, Dhruv!
