Proof of concept mock-up. High-mounted display of motion, randomized. Wind powered. As I rode behind the user, he was much more noticeable and cars seemed to slow more before passing.
Testing the electronic mock-up before fusing the rubber prints.
Riding behind the user in daylight, the electronic mock-up was effective in conveying motion, but the LEDs should be brighter. The next mockup will include thinner or clearer rubber lenses along with brighter LEDs.
