This was just launched today. It's pretty basic but it I LOVE the UI -- the purple, animation, so sleek. I also love that Diddy is making his fans a part of his movement; really smart branding. Basically, it allows you to upload your photo & comments to become part of the "Last Train to Paris" (Diddy's new album out later this year) mosaic; later, they'll launch a full app where you can see which photos were selected for it, read people's stories, and more stuff. It also feeds Diddy's (highly entertaining) Twitter updates. It's free here http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=309246841&mt=8 What do you guys think??
