Galaxy Spatioplotter for Mac1.06

Galaxy Spatioplotter generates a galaxy using a newly developed algorithm. It is a simulation using three basic observation and theories: "Galaxy Rotation Curve", "Stochastic Self-Propagating Star Formation (SSPSF)", and "Density Wave (DW) theory" Combining those three theories, it is possible to explain various shapes of galaxies, such as spiral arms and bars, and possible sequence of evolution of the galaxy.
