### Summary ###
# using a black/white png, you can simply load in the
# 8x8 map you want.
# this makes it easier to create images, sites like
# pixilart.com/draw can allow you to create these 8x8's with ease
# note that a black pixel corresponds to an ON led, while white is
# an OFF led
# Any other will just be on/off, without any way to tell which beforehand
