It just looks like a scarf. But it still seems pretty amazing. Have y'all seen this already? It's been flooding my internets for days. Two Swedish students-turned-businesswomen have invented a bicycle helmet that instantly inflates when you crash, like a head airbag. It is kept under a fashionable outer wrap and activated via "accelerometers and gyros." Here, see video:

A longer video that is mostly interviews with the helmet's creators is right here. Here is the website for the invis-helmet, which is named Hövding.

Thanks, Slog Tipper Jon E.!
