Zedshaw riffs on pentatonics

I was up 'till 3:30am last night because I had figured out something incredibly cool about music on the
guitar.  If you take the intervals in major pentatonics you get:
  C D E G A C = ww(m3)wm3   so Whole Whole (minor3) Whole Minor3.

So a minor pentatonic is the same intervals, just shuffled over:
  ACDEGA = m3 w (w) m3 w

Same interval setup, which makes sense.  Now, if you do the same thing with a 5 note dominant arpeggio
you get:
  GABDFG = w w (m3) m3 w So a new ordering of the same intervals.

But then take the half-dimished 5 note arpeggio and you get:
  BDFGAB = m3 m3 (w) w w

Same ordering as dominant arpeggios, just shuffled.  Which means that major and minor pentatonics are 
the same/related, and dominant and half-diminished are same/related, but shifted.  I then spent the
whole night figuring out 3-note-per-string scales for dominant and half-dimished arpeggios similar to
my pentatonic ones.
