 This puzzle has two 1c pieces that are physicaly represented by one 2c piece (the core). Technically the puzzle is solved only when all of the other pieces have the pink sticker on the outside cell (because pink is outside on the core piece). To be able to solve the puzzle with purple color facing outwards, Tymon created a gyro algorithm that flips all pieces inside out and puts the core outside of the puzzle. This represents that pink/purple axis is flipped and now the puzzle is only solved when all of the pieces are oriented with purple on the ouside. The gyro can be reversed to get back to default projection.

 ### Invention
 Many hypercubers, including [Melinda Green](https://superliminal.com/) (one of the developers of MC4D) wanted to create a physical 3^4^, but sadly it just seemed too complicated. Eventually, she decided to focus on the 2^4^ due to its simplicity of only having 16 4c pieces.
 
-Throughout 2013 and 2014, Melinda was in contact with [Oskar van Deventer](https://oskarvandeventer.nl/), and together they tried to think of any possible mechanism for a physical 2^4^. Originally they were determined to find a good mechanism that didn't have to rely on magnets, but after several failed attempts a magnetic mechanism was the only solution. In 2017, Melinda built the first prototype and shared an unlisted [YouTube video](https://www.youtube.com/watch?v=Asx653BGDWA) showing it off to the mailing list members.

 A few months later, Melinda built a 2nd prototype using 3D printing from a company called Shapeways (which just so happened to offer 8 colors, 6 of them being standard Rubik’s Cube colors, plus pink and purple (this is where the standard 4D colour scheme comes from)).

 This is when Grant joined the server, and shared his 3D printed 2x2x2x2. Rowan then challenged him to build Luna's design for the 2x2x2x3. After a lot of time tweaking the designs, printing them, magnetizing them, and assembling them, the 2x2x2x3 was completed on February 3rd 2022.

 After the invention of grant's 2x2x2x3, hypercubers were already thinking about what was next. The 2x2x3x3 has an extra middle layer that the 2x2x2x3 doesn't have, which introduces the 2c piece to the design. Hactar designed the new 2c piece, and then Grant made the first rendering of what a physical 2x2x3x3 would look like.

+In order to prove that it was fully functional, it had to be shown that moves matched the virtual puzzle, and that it was possible to gyro the puzzle into different orientations.
 
 The gyro starts by removing the middle layer, and then gyroing just like the 2x2x2x3, which involves separating that middle layer and then gyroing like a 2x2x2x2. Next, the middle layer has some 4 dimensional black magic done to it, and then finally the puzzle is reassembled into the gyroed state. After doing this, Grant realized that some of the 2x2x3 cell moves aren’t accessible, meaning that we actually need a 2nd type of gyro! This secondary gyro involves centering a 2x2x3 cell, and then making the middle layer stick out. Now the puzzle was fully functional.

 At first, it was not clear how to expand the physical 2x3x3x3 into the 3x3x3x3, as it would need extra pieces that would no longer make it a nice cuboid shape. This is because we have one more slice layer than the number of dimensions we're trying to simulate. For example a 3x3x3 has 3 slice layers, so to represent it in 2D space, some of the pieces have to stick out like this:
