Wall Art
========
This is a CircuitPython port of an art piece I have
hanging in the wall of my office, with
This an art piece I have
hanging in the wall of my house, with
pixels crammed into a cardboard box.
This port is running on a 1x1 stick of wood,
with tissue paper around it.
It doesn't display anything significant.
The idea is to have something to look at if you're idle,
without it being a distraction from more pressing issues.
