2001:
- The crescent moon (made of cheese...), is viewed from an non-earthly angle. This effect is achieved by taking a boolean difference between a sphere and a cylidner.
- The ship is made of a number of unit cones and a unit cylinder, that have been translated, rotated and scaled. It is made of a brassy metal, a reflective black, and an orange flame.
- The obelisk is a scaled, rotated, translated cube, in (of course) a reflective black.
