Researchers at Nottingham and Sussex university have developed a new kind of interactive wall display for community file sharing in public places, called Dynamo. The idea is for it to be installed in public places, where you just walk up and sit around it with a group of friends, connect whatever personal devices you may have on you (e.g. laptop, camera, smartphone, etc), and share multimedia with each other. What makes it different is that it's multi-user, so you all get your own coloured pointer on the screen. It's intended to provide a fast, easy and sociable way of sharing and exchanging files (from office documents to multimedia) while face-to-face. It also provides noticeboard functions, allowing you to post up items for others to take copies. It's a neat idea, a bit like a cross between a noticeboard, a jukebox and a multi-user desktop. The website describes the system in detail, offers a demo video, and the option to download the dynamo codebase, which was implemented in Java/C++.
