14. The Janko keyboard
The Janko keyboard is an alternate musical keyboard layout for pianos designed by Paul von Jankó in 1882. Each chord, scale, and interval has a consistent shape and can be played with the same fingering, regardless of its pitch or what the current key is. If you know a piece of music in one key you can transpose it simply by starting at a different pitch because the fingering is the same in every key. Here is a demonstration.

And what if this wheel had strings for spokes, could spin, and when played, would sound like the wind?” Source.
