Loading...See through ePaint that takes on the colours of the image projected onto it
Street ads that just need someone to project an image on to it for a second, click save and the pigment in the see-through paint changes colour, would save heaps of time for bill stickers who want to switch ads quickly. Not sure if its been invented yet though.
Wouldn’t a smart changeable LED sign board be a much better solution?
nice idea, especially if it looks like chameleon paint if nobody is advertising on it at the mo. or it might just look white or dirty, in a city.
