Today I found myself annoyed at the traditional design of the piano keyboard. It makes tasks that should be straightforward, like transposing chords and melodies, take up a lot of effort, and it is hard to get a physical feel for each chord type -- one has to learn each chord _in each key_. So I ended up going on a rabbit hole learning about the Jankó keyboard design. Here is someone who got proficient at it demonstrating how it works:

This weekend I discovered a webpage that generates these puzzles, where the goal is to draw the unique closed loop in a square grid, subject to constraints on how many times you are allowed to pass next to certain tiles. There are various difficulty levels, and you can also choose among many other tilings (even the hat monotile!). These are very satisfying to solve, but I also find them quite addictive, so try them at your own peril!
