The Swedes are one of the top designers in the world. I just watched a video of them developing an Invisible Bike Helmet. I definitely think it's worth watching so have a look: https://vimeo.com/album/2148760/video/43038579
They took a incredibly important issue of wearing helmets whilst biking and did an impressive job of completely re-designing and engineering it incredibly well. Do you think this will be the helmets of the future?
