We met in Munich at Docomo Euro Labs to start a new project that is related to context and ambient visualizations. And everyone already got bunnies 😉
Related to this there is a large and very interesting project: IYOUIT. Besides other things it can record and share your context – if you have a Nokia series 60 phone you should try it out. As far as I remember it was voted best mobile experience at mobile HCI 2008.
