Solved my cube in about 15 minutes. It's a record as I just started learning a couple weeks ago. I know there are folks solving in second but it is not my time yet. #BlindCuber #RubiksCube

I was unaware of the hashtags, but I'm in! Just joined #RubiksCube and #speedcubing tags.
I've just started translating the book concerning Rubik's cube tactile version. You can find more information on https://tactilecuber.com - the author is Paul Martz, a 62-years-old blind man who bought first cube in 1980 when he was still sighted. I'm born blind instead, and waited 34 years for a tactile-based resource about the cube. Till spring 2025 there wasn't any resource in English as well, before Paul published his book. Now, I'm going to translate it in Italian as well, to provide it to all #blind related associations around the country. I also have started sort of Italian written blog where I share my #cubing adventures. I also ping @nationsblind who I suppose are aware of Paul's efforts. And also @BPI Blind LGBT pride international association where I'm a member and would like to cooperate in concrete ways rather than talk and talk.

PS wondering if there are Italian cubers here around #fediverse

mention @mastoblind group to make other blind folks aware.

@elettrona @nationsblind @BPI @mastoblind

I guess a mirror cube (it's how it is called, usually it came with gold or silver sticker) can be a cheap substitute.
Sighted people buy it because unscrambled, on a table, it looks great

@luca @nationsblind @BPI @mastoblind It's plastic made. But it has textured tactile shapes on it: one face is smooth (generally the white), another has squares, another has full circle, another has 9 dots for each cubie, another one has crosses (plus signs), another has empty circles. Unfortunately there are no conventions for tactile cubes, but in his book, Paul Martz suggests that if you want to 3D-print your custom textures, you shouldn't use direction-dependent symbols. I mean, figures which change their feel when you turn them by 90 degrees. A square is OK, a circle is OK, but not a rectangle or triangle. A 5 pointed star, might be OK, an hexagon as well. A cross should have its 4 arms of same measure and perpendicular. That's why I said "a plus sign", because generally the X has two small and two large angles.
Even though there is no convention on tactile shapes for cube, having direction-dependent figures might change your mind's focus. You concentrate more on how the piece is turned, than in the cube's information itself.
For instance, do you need to solve an edge? You must find the cubie meeting this criterion: its 2 perpendicular faces must match your down-side and front-side centers.
My first cube, built by my best friend, has direction-dependant shapes and I found myself stuck, as I had to find the capital-T shape, and arrow-shape. I gave up and took my other cube. #RubiksCube #speedcubing #accessibility #a11y #blind

This had me captivated for a good five minutes. I just kept watching how the patterns matched up, trying to parse out the connections in my brain.

Who knew an animation of a Rubik’s Cube and some corresponding concentric circles could be so stimulating?

I have absolutely no idea who created it. Tried to find out to no avail. (Happy to edit with a citation if someone knows.)

A Rubik’s Cube, depicted on the right as a three-dimensional rendering, is modeled on the left as a series of overlapping concentric circles. Each sub-face of the cube is a colored dot, and each rotation of the cube corresponds to a rotation of the dots along one of the circles. The dots always fall at the overlaps of two circles, representing that they can always be moved in two different directions.
