A simple trick to design your own solutions for Rubik's cubes
Mathologer
Mathologer shows a simple idea, the commutator, that lets anyone who can solve the first layer design their own full Rubik's cube solution. The same idea carries over to other symmetric twisty puzzles such as the Megaminx.
Recommended as an accessible explanation of how Rubik's cube solving relates to group theory.
