Cool! This is a great way to visualize the relationship of notes in a chord. One of the harder things to teach in beginning music theory are chord forms, since it requires thinking relatively, rather than absolutely. Major and minor chords are related together not because of the notes themselves, but because of the intervals between them.

In this visualization, though, all the related chords are roughly the same shape. Seems like it'd be a great way to harness visual thinking to teach a more abstract concept.

Very cool!

Two-dimensional keyboard layouts mostly use regular chord shapes. It makes both theory and playability come a lot more easily - two fingerings per scale and chord, no adjustments for different keys. I own an Axis 49 and while I'll admit it isn't perfect for existing repertoire, it excels in every other respect. If you want to "learn music" this is the fastest way to do it.
