This is a 3x3 font. It's about as small as you can get,
and it isn't really even readable. But if you need a quick
font for a LED matrix, this should work.
It contains uppercase A-Z and a few symbols. It's written
in the same format as https://github.com/petabyt/font/.
I designed this for use on the ScrollBit, but never got around to
using it for anything interesting. Feel free to use it under the MIT.
