Someone linked [1] an interesting tool in the replies: <i>MagicTile - Geometrical and Topological Analogues of Rubik&#x27;s Cube</i> - <a href="http:&#x2F;&#x2F;roice3.org&#x2F;magictile&#x2F;" rel="nofollow">http:&#x2F;&#x2F;roice3.org&#x2F;magictile&#x2F;</a><p>&quot;If you want to try solving the Rubik&#x27;s Cube this way, you should try @roice713&#x27;s MagicTile. You can choose the Rubik&#x27;s cube among hundreds of puzzles. The stereographic projection makes it look like the animation in this post.&quot;<p>[1] <a href="https:&#x2F;&#x2F;twitter.com&#x2F;mananself&#x2F;status&#x2F;1595132523264167936" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;mananself&#x2F;status&#x2F;1595132523264167936</a>

As someone who as held national records in the sport of speedcubing, I don&#x27;t feel this makes it easier to understand, at least if you are going for an instrumental understanding of how to solve it. I think the community are pretty good at teaching that now! But it does look extremely cool.<p>My favourite one-liner for improving understanding is something roughly like &#x27;solve areas made of pieces, not faces made of stickers&#x27;. Very much clearer when you have a cube to take apart and put together in the order you would solve them.

Was trying to make sense of that solve, but couldn&#x27;t see any algorithmic thing happening. Either that&#x27;s the craziest method I ever saw, or it&#x27;s just a reversal of a random scramble.<p>Regardless, none of that takes away from the nifty 2D projection technique!

If I understand it correctly, this visualization does not take into account the constraints of some faces being physically tied to each other, by being on the same cube. So, while it can show the process of solving cube, it is not a replacement for the cube (i.e. you can&#x27;t use it as a simulation to try to figure out new algorithms)

The corners appear as triangles in the figure. I counted all the triangles I could find and was confused because I only saw 7. But then I realized the 8th is around the outside of the whole figure!

I saw this on Mastodon three hours before the $8Chan link was posted here.<p><a href="https:&#x2F;&#x2F;piaille.fr&#x2F;@Mnaudin&#x2F;109389968985022395" rel="nofollow">https:&#x2F;&#x2F;piaille.fr&#x2F;@Mnaudin&#x2F;109389968985022395</a><p>It&#x27;s a really poor representation, for specific reasons:<p>- it doesn&#x27;t convey how the corner and edge colors are constrained into moving together, due to being mounted on the same cube piece.<p>- doesn&#x27;t convey how the center face pieces stay in place relative to each other.<p>- certain rotations &quot;cheat&quot;: the dots dance around, not staying on their orbit tracks.

on a similar note, you can get yourself a 4D rubiks cube (projected into 3D)<p>It is not a 3x3x3x3 but 2x2x2x2.<p>It looks like Melinda (the inventor) have made them easier to obtain. back when I got one, 3D printed parts, magnets, and coating all came from different sources, but absolutely worth it, they are very unique and work well.<p>link: <a href="https:&#x2F;&#x2F;superliminal.com&#x2F;cube&#x2F;2x2x2x2&#x2F;" rel="nofollow">https:&#x2F;&#x2F;superliminal.com&#x2F;cube&#x2F;2x2x2x2&#x2F;</a>

Cube solving is a path finding problem.<p>The way to learn path finding problem is to understand how your actions move you through the space you&#x27;re navigating.<p>One of the most effective ways to learn these relationships is to work backwards.<p>Starting from the goal, take a step away, then step back. Then take two steps away, then those steps back. Then take different steps away and steps back.<p>As you move farther and farther from the goal you get an explosion of options that quickly requires deduction of strategies over memorization of all paths back to the goal.<p>This can help ground learning the well known techniques for cube solving.<p>This visualization <i>might</i> help with that process, but just playing solutions from start to finish (IMO) doesn&#x27;t.

It&#x27;s a spectacular visualization, kudos to the author. However, I&#x27;m not sure it made it particularly easier to understand, although I know that is subjective.<p>Something that helped me was [1]. It took me from being someone who could not solve at all, to actually being quite good-- in the 13-20 second range. The beginner method listed on the site can easily put you in the sub-minute territory.<p>[1]: <a href="http:&#x2F;&#x2F;badmephisto.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;badmephisto.com&#x2F;</a>

This is so beautiful. Changing dimensions is often mind boggling even though it makes sense.

I never wanted to learn how to solve it, because finiding my way to solve it <i>is the game</i>. who&#x27;s like me?<p>I bought a rubik&#x27;s cube when my son was born, because I wanted something to play that was not my phone while he was on my lap. 3 years later I&#x27;m able to complete one face in like 5 min consistently. still a long way to solve it, new techniques to discover and hours of play in sight. yay!

another 2D visualisation of the rubiks cube that is popularly used for computer simulation speedsolving is qcube[1]<p>despite not being able to see all sides of the cube, it&#x27;s surprisingly easy to solve on, as you essentially see the same stickers that you would in real life.<p>there is even an IRC based version!<p>[1] <a href="https:&#x2F;&#x2F;mzrg.com&#x2F;js&#x2F;qcube-v2.html" rel="nofollow">https:&#x2F;&#x2F;mzrg.com&#x2F;js&#x2F;qcube-v2.html</a>

Kind of reminds me of playing the 4D Rubik’s cube

How is this easier to understand? And is the Rubik&#x27;s Cuber hard to understand at all?<p>You got 26 cubes in 3D space that need to go to their correct locations. They can move in 3 axis. They are color coded for recognition.<p>I think anyone is able to solve the first 2 layers intuitively. Just start by following one of those 26 little cubes and see how it moves about.
