I was reading an old copy of the wonderful TV Century 21 and chanced upon a whole page devoted to Identicode, including a crossword!
I’ve included the page below so that you can try it for yourself.
Something I’ve considered adding to Identicode is text recognition using Apple’s vision framework, that way that large chunk of Encoded Blue Text below could be entered directly into Identicode from your device’s camera. It’s never a problem when encoding but as the coded text makes no sense to us it’s easy to mistype.
