That's awesome and based on my experience I'm not shocked this went well. I'm not sure what the features would be in this but I am assuming they could be specific pixel combinations or other things which would be easily labeled in a few ways. I hope you had fun with it.

My previous project was far from that. https://healthverity.com/audience-manager/

I had a lot of fun, really the last fun project I've had. I hope you had fun as well.

in the interest of understanding, is there any code or similar for the approach? does that OCR run anywhere today?
