Ship Decals

After reading the “ship colours” thread I realized, wouldn’t it be cool if there were a simple drawing interface in which you could decorate your ships? After creating a ship you could perhaps draw a simple design on it.

The obvious problems with this are
A) I have no idea how difficult that would be to program and
B) People would likely just draw lewd stuff all over the thing.

Still, I think if it were easy to implement it’d be great to add your own personal aesthetic touch to your fleet.
