Inspired by this, it occurred to me that a bit more advertising is what the world needs.
Today’s invention is a tower block with computer-controlled sliding window shutters. I’d also like to see the effects of coordinated colour-varying interior lighting when the shutters are open.
These allow low-res moving images of famous brands to be displayed across a huge canvas, in full view of traffic streams -and queues.
The images could be played wrapping around a building, not just on one face.
Residents would need to be paid a cut to tolerate the sharply varying interior light levels.
