Design students Anna Haupt and Terese Alstin from Sweden have embarked on a pretty incredible venture: they made an invisible bike helmet.

The helmet, called Hövding started out as a project for the duo’s master thesis at Lund University back in 2005 but quickly became their obsession. In 2006 they won the Venture Cup (over 200,000 Swedish kronor) and the invisible helmet was becoming a reality.

You need to visit their site and watch the video to really understand the design, but basically these legends have made a kind of neckbrace/scarf type product in which lives an airbag helmet. It will detect an accident the same way that a car’s airbag does, and hey presto! an invisible helmet.

Absolutely genius, right?
