#3Probing the conscious and subconscious mind, a novel mind-boggling 3D-to-2D visualization, working interactive demo, nice hand-drawn diagrams - this is my HN nugget of the day. Kudos!

#4> this time I was fixated on how to create a three-dimensional version of Tetris.
I remember playing a 3D Tetris-like game called Blockout back in the day. Some shapes were odd and non-4-block, key mappings for rotations were mind bending.

As for the Tetris effect, at some point I played a lot of Tetris and seeing falling tetrominos when falling asleep was only the beginning of it: my brain built some heavy pattern recognition for pieces, so much so that I was basically daydreaming tetrominos everywhere, as in seeing a tetromino shape first, then realising what the thing actually was (e.g a bunch of buildings, a bunch of cars parked in a certain way, in books where rivers lined up a certain way, or words were even vaguely tetromino-shaped), or seeing stacks ("I could fit a T in there" and stuff).

Yes, the main keys were Q/A, W/S, E/D for rotations around the major axes, arrows for moving in the XY plane (assuming the Z axis is "down") and SPACE was a force drop I think?
You can learn a lot of Group Theory trying to make a mental model of how the rotations work, since you get not just equations like QQQ = A but also (from memory so maybe wrong) something like QWQ = D. Shapes with symmetry axes generate subgroups, some (like the I block) even commutative ones. So technically you could live with only three of the rotation keys if you're the kind of person who rotates left three times when you want to rotate right.
And of course, the 3D versions of the S/Z pieces can screw up your game even worse than the 2D ones.

I played that a lot, too! Usually with the simplest block set, which was just 3D versions of the usual Tetris blocks. After that, playing “normal” 2D tetris suddenly became harder, because there are some rotations that cannot be done when you have only one axis! In 3D, you can flip an S into a Z, but in 2D, you can’t!

Haha I did that a lot! the sequence became hardwired in muscle memory, like when you learn to solve a Rubik's cube and moving this to that becomes second nature.

I didn't have a clue what group theory was back then (I was 10yo or something), but I clearly remember discovering these. Pretty sure it ended up become formative for my surprisingly quick group theory understanding in later maths class.

One of the earliest "too soon?" jokes I saw on the internet was a 2002 or so animated GIF of a game of Tetris being played around and between the World Trade Center towers: https://knowyourmeme.com/photos/172830-september-11th-2001-a...
