For the past two days, I've been experimenting with making an input method that allows me to draw glyphs as keyboard replacement.
To reduce mistakes, I've added alternative shapes for some of the characters so if I miss a direction or two it still understands what I'm trying to type. The whole whole thing is a tiny 1.6kb rom.

@neauoire reminds me of the palm pilot script. :)
