That's exactly what I was going to say - the "hand drawn" diagram on the right is better looking, but the left hand is far more accessible and arguably have more utility.

That said, this is a really cool demo.

MyScript offers an API that does this. You need to feed it all the motions/sequence of points that make up the shape (known as "online OCR"), it won't work with a static document.

There are tools available to draw ASCII diagrams easily, like asciiflow.com or asciidraw.com. Their output can be directly pasted into ShakyDraw.

I was just thinking that. It should go both ways :D
