Relativistic Starflight - The program xrel depicts, as realistically as possible, the appearance of stars as seen from a starship moving at speeds close to the speed of light. OpenGL Relativistic Spacetime Project - A real time relativity simulator for Windows, Linux and OS/2, using OpenGL. Warp Special Relativity Simulator - A windows program to show you the weird effects of special relativity. Relativistic Ray Traced Images - Features visualization of relativistic deformation effects of a spaceship like object. C-Ship - A short overview of special relativity, filled with relativistic ray traced images. Explains relativistic effects using a theoretical spaceship. Visualization of the Theory of Relativity - Online papers, images, movies and paper models. Interactive Visualization of Gravitation as Spacetime Curvature - Interactive Flash animation of a smaller test mass in the gravitational field of a larger mass, following the laws of general relativity. The animation uses an unusual form of representation in which time is bent into a circle.
