No, the dimples on a golf ball turbulate the boundary layer so that
on the rear face you don't get laminar flow separation. The separated
region will be larger for laminar flow than for turbulent
hence more drag.

"like a golf ball, maybe is an aerodynamic improvement!"
funny, but does it need to spin?

True, but it was a joke Mike, in the same vein as Richard F would have
known that the nose dimpling would not behave as a golf ball and hence no
aerodynamic improvement would result.
I'll be sure to include a smiley next time though :)
