Close Encounters of the Egg Kind

Okay, it's a bit silly, but there really is a giant 'egg' down at the port. I saw it for the first time today. I guess it's for storing something (maybe a spaceship). Anyway, there was a lot of ugly things in the way, like signs and cars, and roads, so I went for an abstract look, to get rid of the detritus.
 And it's all I've got today.
