It’s common to see buses travelling slowly side by side in city streets or parked in parallel.
Public transport is increasingly used to advertise movies, so that all the buses in a given district will carry the same adverts.
Today’s invention is therefore to apply a stereo pair of images to the back face of buses -to advertise a 3D version of some forthcoming movie.
People watching these vehicles would be able to cross their eyes a little, fuse these images and see a stereo advert.
This could be enhanced by applying the images to buses known to pass each other on certain regular routes.
