It [1] is the cutest handwriting I have seen and it uses Braille as the ink. When we use it's handwriting, you actually see it writing (0:06), not just the final result. You can type in or stdin the text, and it even gives you a special segfault writing when it's not able to write (0:35).
As for the "triCk" or secret in handwriting, unfortunately, it's "LOCK"ed (0:03) away from me.
