It was one year ago today that David Smith emailed me out of the blue, asking about my work on computing Heesch numbers. A few days later he tipped his hand and showed me a drawing of the hat polykite for the first time. Happy Aperiodic Monotile day to all who celebrate.

@csk I just watched the “Up and Atom”YouTube vlog on this. With excerpts from interviews with you and Dave.

Dave is a f****** legend. :)

Have you ever met him? If so? What’s he like in person?

@nikolaihampton Yep, Dave's a legend! I met him in person for the first time (and reconnected with @Chaimgoodmanstrauss) earlier this year at an event in Oxford (where the Up and Atom interviews were shot). It was lovely to spend time with both of them.
@csk @Chaimgoodmanstrauss has there been any more work on finding other mono tiles of a different recipe? Is there anything about Dave’s (and your) tiles that suggest there will be other families?
@csk @Chaimgoodmanstrauss I’m also extremely curious about what was it that fueled Dave’s intuition to look at this particular shape. Surely it couldn’t be brute force? It’s such a fascinating story.
