That's pretty cool, although I admit that without those captions I would not be able to read the letters. Do you want to go ahead and make a bigger one?

I based my fonts on this:

It was the only 4x4 font example i could find, too bad 4x4 can't make all letters really readable tho, 8x8 would be better.

I probably will create a bigger one (8x8) when i received all my parts (more shifters etc..)
