Motorways are equipped with various configurable signs on
overhead gantries. Some of these signs are single-colour and
designed to display simple text messages ("Fog Ahead - Slow
Down"; "Lane closed ahead"; "Whelk on Sliproad" etc). Others
are a little more complex and can display black-red-and-white
road signs such as temporary speed limits.
Most the time, these displays sit there blankly staring at
oncoming traffic because there is no fog and no whelks. What
a waste!
Instead, therefore, why not use idle signage to display basic
but useful facts. For example "Human Genome: 3e9 bases", or
"Prime numbers are indivisbible", or "Deimos, Phobos: moons
of Mars". Facts can be updated every few hours.
Prior art?
