Nice! At Keplers in Mountain View you can buy version of Scrabble that uses regexes. The designer used to sell it in front of the shop -- he is obviously a programmer.
It wasn't a short-term item, but poor Kepler's has shrunk so much who knows if it's in stock or not. I would call them. It wasn't described as using regexes of course, so you'll have to say something like that special version of scrabble.
The designer is local so if they no longer stock it you could look online...but it's better to get it from the shop if you can.
Never played it, but from looking at the box of talking to the inventor it was just that The set of letters included regex operators and those The set of letters included regex operators and those you could put on the board as well. Meaning other people could use him as well To make words.
