Goals:

Give the customer (the world) what they want

Features:

		Comprehensive implementation of special relativity (Lorentz transformation use complex quaternions)
		Comprehensive implementation of the complete Reissner-Nordström geometry, including wormhole and white hole connections to successive universes
		General relativistic volume rendering
		Comprehensive implementation of the general relativistic motion of the observer, and of arbitrary numbers of objects moving in the geometry
		Interactive control of the motion of the observer and of numerous aspects of the scene
		Bison Fightpath Interpreter allows total control of every aspect of the scene and flightpath
		Able to render to arbitrary single- or multi-piped graphics configurations
		"Aggressive memory management" option allows complex scenes to be rendered with limited memory
		Numerous accelerations, fast algorithms, and graphic refinements to achieve seamless high-quality rendering while maintaining maximum speed (for example, the volume-rendering uses randomly staggered meshes to reduce artefacts associated with regular meshes)

To do:

		Needed improvements: graphics abstraction layer; higher quality volume-rendering; ray-tracing bundles from rigid objects to quadratic not linear order
		Implement Kerr-Newmann
		Drop a star (e.g. red giant) into BH
		Gravitational waves to linear order
		Hawking radiation
		Reflecting/scattering surfaces (general relativistic, of course)
		Make it writable by an astrophysicist
		Make it usable by a 10 year old
