Displaying messages with only 7 (or 4) LEDs on a stick...

I always wanted to make a strip of LEDs that was on a truck body or mounted on an upright pole on a motor vehicle. This single strip of LEDs would be synchronized to the speed of the vehicle. People standing on the side of the road would see the full color “banner” poster, as it swooshed past them! Or Maybe, a single pole beside the highway. A single strip of LEDs that could be synchronized to the speed (read by RADAR) of the vehicle. The people moving by would see a full-length bill board, but the “sign” would be a single piece of conduit. No wind loading no blocking the scenery. Probably not enough speed for the illusion, but a fun “what-if” experiment.....

You'd have to focus out in the distance to keep your eyes from tracking the object up close.
Neat idea, and has obvious advantages...but I don't think the average human being operating the average human eye would actually 'LET' it work...unless of course they'd been drinking
