Golfball-like dimples are only half my question. In aircraft much work has been done on reducing boundary layer issues with suction holes that actively remove turbulent air. Some aircraft engines, the SR-71's in particular, do this to ensure 'clean' intake air.
Speaking of the SR-71, you guys should all read the heavily reposted stories about it. It's such an amazing plane. While it's not flying in the sky anymore, it deserves to fly in our imagination every time somebody speaks about it.
