The spirals are shifted so that pushing a slider not only changes the key signature, but also takes you to the next note of the scale like a slide diatonic.
The key of C has diatonic slide decorations at every note, and most other keys have them at all but one or two notes.
So to describe it with a few basic selling points:
* Chromatic!
* All the chords!
* Any key with at most one slider note!
* Acts as a slide diatonic in most keys!
