Spoke n' light
On Sunday 19 and Monday 20, students of the Interactive Telecommunications Program (Tisch School of the Arts in New York) will present their work at the Winter Show.
I had a peek at the projects and spotted Michael Kertesz ' Bicycle Wheel, a system that could be applied to increase cyclists' safety and pedestrians' entertainment.
He mounted thin a strip of 32 LEDs on the spoke to create a semi-transparent screen on which images, messages and animations can be displayed. The complete circuit (LEDs, microprocessor, battery etc.) is installed on the rotating wheel.
The mechanism is based on the "Persistence of Vision" (the eye perceives a series of rapid still images as a single moving image) to create the illusion of a stationary image.

very interesting application of LED, however, do we know if the velocity of the wheel is limited by the LED image? that is, can the bike be ridden fast or slow and still have the same message shown by the leds?
