As we all know, part of Wikipedia's functionality is its organised, categorised and linked webpages (I've lots hours to the art of "wikisurfing" from one link to another). These pages and their links have been rendered as a visually appealing interactive galaxy by French computer science student Owen Cornec.
Typing in a term transports you to the central star from which radiate related articles. It's an attractive way to explore Wikipedia while giving you a sense of how large and interconnected this body of knowledge is. While plenty of articles are not yet included, Cornec has created the ability for users to do so themselves. His next step is to get it working with Oculus Rift for a truly immersive web of knowledge.
