Very hypnotic. I like your way of playing related intervals by adding/subtracting a fixed amount. An interesting way to think about melody.

Might be interesting expand this approach to circle around various starting points, not just octaves. Say, an octave, a fifth, a third, a seventh. Might add more variety to the melody.
