I like the way you think.
You could also 4x the resolution by using half- and quarter-block characters from the top half of the ASCII table (or it'd be the PETSCII one i C64 case).
Now that would be simulating life witg life.
One window = one pixel.
A grid of capacitive touch sensors could be printed directly on the pcb, bringing down costs by a degree of magnitude. Real switches are much more satisfying though.
