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.

Invented and built by Cris Forster, the Chrysalis was his first concert-sized instrument. The instrument’s design was inspired by a huge, round, stone-hewn Aztec calendar.

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