A year or two ago I create this OVNI(UFO) for use on a scene for learn about voodoo camera traking and the integration of objetcs on a video with blender. See the scene here (internal render):

The file here only contain the ufo and the platforms, how you can see on the picture

The file are ready to render in cycles, all meterials setup and some little work on the compositor

Enjoy it!
