I hope the moderator doesn't mind me chiming in here. We have been following the skully very closely and monitoring patent applications not only from them but Google themselves. just google google helmet patents. What we have here folks is the race to the augmented helmet. Basically, sticking your cluster into your helmet so that you can focus on the road ahead without having to take your eyes off it to see that you left your blinkers, low tire pressure etc. the issue of putting something infront of an eye is the ability to focus or having to refocus. Yes, with Reevu you see behind ( even with sport bikes ( it may take some extra time for some)) but what the invention really is...is" The focal length" the ability to position something in front of your eye and not having to refocus. Here is some insight into sticking a beam splitter into a helmet.
