Hey everyone, I'm James, the writer of the linked blog post with the 3D Tetris experiment and I just today discovered this thread! Which explains the bump in traffic I had for a couple of days back in August.

One of the moderators has kindly let me jump back in to say thanks to everyone that read the blog and had a play, it was most exciting to see people talking about it and I was especially amused by everyone bagging on the unreadable font - you'll be relieved that it has been changed, as of a few weeks ago.

So, a huge thanks, you've all made my day. And if you were looking for a mobile version, here it is... https://nonzerosum.games/tetrings_mobile.html

I'm looking forward to being part of this community too.
