This is cool! Few things: Add the words that were already spelled to a `Set` and check for them again when making new word choices. I got "NUMB" three times in a single session. Z's tracking just flat out doesn't work. Q is signed different than I learned it, apparently. I sign Q as an upside down P, but the tracking apparently wants an upside down G. I don't doubt people sign it that way but as others have mentioned this is going to be different for different people. Lastly, I had problems with going too fast. It really felt like I had to strain myself to get it to recognize. More tolerances in the recognition would be nice.
