- Space Engine: travel any where in the universe. Huge a catalog of known object and great procedural generation for everything else.
- Universe Simulator: model planetary and solar systems, even galaxies. Shoot a black hole through the Earth solar system or construct a binary star system for a Tatooine type sunrise.
- Scrivener, first and second look: a powerful tool for writers. Word capture is decent, although a power MSWord-user will notice many missing features. Its real strength is letting to abstract and organize your work by scene, chapter, and section, goal tracking, and lots of other writer-specific features.
