One
I created the different shapes required: a Bowl, a Cone, an Ellipse, Engraved Text, an Inner Tube, a Pyramid, and a Sphere.
Two
I downloaded random objects created by other people from the 3D Warehouse featured in Google Sketchup: a helicopter, Bumblebee, a car, a jet, and the Melinium Falcon.
Three
I then put the shapes in random positions on top of each other. I placed the jet above everything else as if it is flying.
