I posted a review of a book called Peak in which the author trained a guy to memorise digits. He did it by encoding sequence chunks and using mnemonics.
That book also references Moonwalking with Einstein which you might also like - the author taught himself how to memorise in one year and won the world championship at the end of it. He was doing memory palace techniques to memorise decks of cards for example.
Basically if you have the ability to do this stuff then you can encode and abstract the components into something that works for your mind.
I don’t have the spatial capacity to do this particular kind of rotating, could probably train it but it’s not useful to me now.
