Nice! Where does one learn how to do this kind of thing (aside from the fractals)?

Every time I have googled for it, the only method of working memory training that comes up is N-Back.

So I'm happy that the article mentions another method. Apart from playing "Simon" (yes that circular game with lights), those are the only two I know.

Anyone know of any other methods?

Great site! The only improvement I would ask for is automatically opening the articles with the Wikipedia app, if installed.

Could you elaborate on the mental math part - do you do particular exercises?

I have some interest in the topic (thanks to Arraycast and Conor Hoekstra) and bought to Mock a Mockingbird by Raymond Smullyan, however it is still a bit too involved for my small brain.

On the other hand, I am very much enjoying How to Bake Pi by Eugenia Cheng, which is a few levels down in difficulty.

Or "smurf" or "smeg".
