Very cool hi-bandwidth Site that combines Flash and Video
This Vodafone-sponsored site, Future Vision, is a very interesting look into the future of mobile computing and where we can go. It does a fair amount of "interactive" visuals which highlight how super-connectivity would be if it was ubiquitous.
Also there is a magazine, Reciever, that futurists write about and pontificate about our "TO-BE" mobile toolset and its social impact.
