Here I have put together a slideshow of the social aspects of the OLPC UI. I gathered the stills and information from the OLPC wiki. (The video is a mock-up of how the UI would work, if it were implemented yet). The Sugar UI is very adventurous- no other desktop in the world gives social interaction such prominence. I just hope they have done, and intend to do lots more user testing. It’s too bad they haven’t done any user testing yet! The intended user-groups need to try out these laptops and give feedback on the things they don’t find easy or useful to use. After a few design iterations, then the laptop might be ready to ship.
There is also a YouTube version here although the quality is not so good.
