looks like the idea cam from a golf ball. basically the same idea, a golf ball w/o dimples just curves and doesnt stay straight because of turbulence that builds up behind the ball in the air. the dimples take away the turbulence to allow it to fly striaght.

Actually, the dimples cause the flow to become turbulent which results in the flow separating later, allowing the ball to fly farther due to less pressure drag.

Yes, I am a geek....
