So, I found a golf ball with mystical lines drawn on it : there's a vague memory of a 45degree Rubik's cube idea (or maybe it was a segue from another idea). Anyways, I'm trying to find that idea.

Also, the one about coal in Tibet.

Halfbakery: Rotaty cube Rotaty cube
"45 degree Rubiks"? I searched quaternion cube because there was something interesting about the non-commutative property of rotations in different axes or something like that. [zen_tom, May 06 2020]

       So, a Tibetan yurt city is all smoggy because of the brown coal they use and inefficient stoves/heaters. HB'ers came together and suggested improvements, quite a few of which didn't involve bulldozers or high explosives.   

       As far as the Rubik's wotsis is concerned, I don't remember much except figuring it out on a golf ball, which worthy I found the other day (month, actually).   

       Also, I was looking for [MB]'s spare driveway post, but anecdotal evidence points to it having long been deleted.   

       Just a bit of rest and rumination, is all.

       So, "Rotaty Cube" it is... not sure I can get back into it enough to figure out where I was. Thanks [zen_tom}   

       Aaand the Tibet one ; thanks [kdf]

       My pleasure [FT] that was one of those lovely ideas that really sparked a proper exercise of the mind. The halfbakery at its best.

       We'd accuse you of plagiarism, except we stole that line from someone else....

       That was my post FT. Mongolia not Tibet but close enough....

       Yup [AC] couldn't remember who, and was too embarassed to ask. So, did anything become of it ?
