Video: Bicycles with lights ringing their back wheels and expert visual editing basically turns regular mountain biking into light cycles on The Grid in Tron. It's already a cool effect in real time because the lights start spiralling with the wheels, but reaches another level of awesomeness with some editing in post-production because the frames get stitched up to look as if the light were leaving colourful trails in nature. I wish this actually happened in real life.
