Actually, you can get a LOT of cool scales if you start the G harmonic minor scale on the other notes of the scale, too. My personal favorite is starting it on C:
C D Eb F# G A Bb C
I really started digging using the harmonic scale a lot a couple years ago. You can use this scale for just about anything to add an exotic flavor. As for the original post and replies, you can look up "scales" under google, and find scales that are not the 7 modes of the major scale. There are a ton out there! Good luck!
