A project log for Paper Pixel Display Array

A stack of standalone units that can display all combinations of 4 (2x2) pixels.

The strip used as a closed loop has 32pixels in two rows which when taped together can display all combinations of 2x2 black and white pixels. If someone can make it more efficient let me know.

I think 16 rows is optimal, good job :)

16 rows, for 2^4 combination : pigeonhole theory says you can't do better.

Prove me wrong :-)
