I have always known quite a bit about aircraft and aerodynamics, but there is something that I have never quite figured out. What is the difference between raked wingtips, blended winglets, wingtip fences, etc? I am guessing that they each have traits that benifit certain aircraft over others...
I have wanted to do this for a while but cringe when I see the cost of the commercial systems. I want to be able to make lights flash in sync with mp3s on a computer but do not want to spend a lot of money. I know there are visualizations incorporated into Winamp, Windows Media Player, etc...
