Nice demos. This is what "literate programming" should be like really :)

It is unfortunate that it can't recognize lowercase/uppercase, and that F and X have to be drawn in a quirky way to be properly recognized. Also I had problems with inputting "K".

I also had problems with "K"; I think the issue is that it does not recognise strokes where the second direction is right (rather than up) as a "K".

Nice demo. I've never been able to get it to recognise B, no matter how I draw it.

It didn't work with how I normally write B either (drawing downwards from the top-left corner), but I did find a method that worked: start at the bottom-left corner, move up to the top, then draw a "3"

Thanks! I'll take some time this evening to make it a bit better at picking out the K.

I'll take some time tonight to make it a bit better at dealing with different shapes of Bs. If you want to know what the 'canonical' stroke pattern is, you can click on the little graphics above the tablet. They will animate to show you the expected stroke path (although, it should just work, so I'll fix that tonight)

Same thing for me on O. I tried clockwise, counter clockwise both failed.

Then I tried starting from top instead of bottom. Don't people start from bottom? It should be easier to align.
