Prototypes

Throwaway code. Each prototype answers one question; the answer goes in its NOTES.md.

• P1: Alive: can a pip built from primitives feel alive and charming?
• P8: Look: a 90s anime look, Frutiger Aero, or toon-shaded low-poly?
• P9: Garden: what does a garden with height, water, mud and caves give wuzoos to do?
• P10: Island from data: can the island be generated from data, as good as P9's hand-built land, and checked by its place tests?
