Well that sure looks similar:

I rotated the inner ring to capture the sense that (for example) Amin shares two notes with Cmaj and 2 notes with Fmaj, so belongs between them.

You can drag the chord gear, click it for a kind of awful synth-piano sound that I had a lot of fun making, switch modes, etc. I actually originally made this in wood/acrylic:https://docs.google.com/document/d/1lwIS-1sPNyIpYM1nCcFkU9Iq... but I like how the online version renames the notes sensibly.)

Mostly I was just trying to explore music theory concepts, and have a few other toys at https://pine.fm/music

(also the code is gross; I've been a manager for almost a decade now and am rusty; you've been warned, lol)
