This is the growth of 2 plants mapped algorithmically to sound. The melody is played by the following context sensitive deterministic L-System:
w: F1F1F1
p1: 0 < 0 > 0 → 0
p2: 0 < 0 > 1 → 1[+F1F1]
p3: 0 < 1 > 0 → 1
p4: 0 < 1 > 1 → 1
p5: 1 < 0 > 0 → 0
p6: 1 < 0 > 1 → 1F1
p7: 1 < 1 > 0 → 0
p8: 1 < 1 > 1 → 0
p9: + → -
p10: - → +
where w is the axiom and p1 to p10 are production rules much like formal grammer string rewriting mechanisms. If the rewriting in an L-system can be considered the plant growing, then the music is the sound of botanical growth accelerated such that 4 weeks becomes 1 minute. (innit).
