Lex is an interesting tool for displaying illuminated messages you can see while the wheels of your bike.
Connects to PC via USB to program the message you want. After attaches to the wheel and you use your AA battery for 96 hours.
The utility may have, apart from doing grace with your fellow outputs or as a way to be more visible on the road, is advertising. Imagine the name of the sponsor of a team showing at the wheel of a showy and flashy so while television focuses on the full trip.
We'll see if it is used in the future ...
