I saw this contest and thought about combining my passion for my career working with aircraft engines and computers (I work for GE aircraft engines). The GEnx engine has a beautiful composite fan blade...the black blade surface with the metallic leading edge.
For a more detailed description with some animation and descriptions...click on the FAN section to see the blade itself.

I could easily see a single blade with the ION board in the base mounted vertically with outlets and buttons on the side of the airfoil surface.
Cheers
