This uses a rotating bank of LEDs like the rotating displays.
This device is mounted on a wheel with the circuitry counterbalancing the lights. A coil mounted on the rim passes a fixed magnet on the fender or fork that tells both allows the device to orient the image the right way up and also provides

spinning disk mechanical tv
1920's mechanical tv system used a blinking light behind a spinning metal disk with a spiral of holes drilled in it. [macrumpton, Oct 04 2004, last modified Oct 21 2004]
||It would also be illegal to use whilst driving (on public roads), but i can see this appealing to the neds!
The idea gets a (-), but as a marketable product it's a (+).

||This would look silly. Imagine how much it would ruin the look of a lovely Bentley.
||If so, I wasn't around and my search didn't bring it up. If someone posts a link, I'll happily delete the idea.
||I made something similar to this in
1976 for an art school project. I
attached a row of 75 leds to a spinning
arm activated by a row of contacts that
skated on a glass disk. On the disk I
could make designs in adhesive copper
foil that would be reproduced in the
||Since then I have seen frisbees and
other flying toys that used a similar
concept as well a clock that showed the
time using an oscillating wand that had
leds on it.
||The whole concept is very similar to the
early experimental tvs that used a
blinking light behind a spinning metal
disk with a spiral of holes drilled in it.
