User generated wallpapers/screensavers

I went along to the Adobe Mobile and Devices user group the other night, kindly hosted by Adobe at their Regent Place office. All the presentations were great. For me though, the most interesting was by Ugur Kaner an interesting and fast speaking Fin :-) He was demonstrating Pikkoo.com, a brilliant way for users to generate their own animated/static wallpapers and screensavers, and for them to be delivered in the correct format for their own device, whether it be a .swf file, animated gif, etc. 

The application can even be hosted on separate branded sites, opening up the opportunity for agencies to create branded templates, for users to go in and create their own design from the supplied assets. I hope I've got all this right!! but it really looks a cool and easy way to generate content for mobile. And thats a great idea. I hope they make loads of money :-)
