An egg on an egg.
I started with the original artwork from: http://www.openclipart.org/detail/18251 and made it Egg-Bot friendly.
I'm not entirely sold on the cross hatching in the black outline, so I may make some edits to this in the future. (OK, see "Egg Egg 2" for a version with 2 solid black lines without hatching.)
