I have some ideas myself, they are not the best and kind of prototypes.
The last two need a bit of work with the cpu design thingy bit. I just got a simple electron microscope picture from google, but a design like the one used by NDxTreme on the wings would seem like something soothing. The first use a bit of colour, but they are just basic ideas. There are design here I think I like more already, but I leave that up too you guy.
