The temple shown here is based on the idea of constructing using only a very limited number of shapes, but then allowing deformation of those shapes. Can you work out how many basic shapes are used?
The light is a testbed for shadows. The lighting itself consists of two parts: a generic bulb light which simulates radiosity and general illumination; plus the shadow generator which surrounds a bulb with a series of vertical slits, causing the shadows.
You might be wondering what a temple like this is doing on a planet that is essentially seen as little more than a rubbish dump and anchoring point for the Lift - and that's exactly how it is going to be until the final release of the manga/movie!
