Backlight - BACKLIGHT is a photorealistic relativistic visualisation system. Developed at the Australian National University by undergraduate student Antony Searle , it produces images and videos demonstrating the optical effects of special relativity.

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.

Relativistic Flight Simulation - A collection of links to various programs which simulate the effects of relativity

Numerical Relativity Exhibitions - What if you take a supercomputer and put it to work on Einstein's theory of relativity? You'll get an incredible series of images representing black holes, gravity and Einstein's equations. This is what happens at the "Numerical Relativity Exhibition", a site from the National Center for Supercomputing Application. Take a peek at this trip into the heart of the universe.

The Cactus Code - A modular manageable high-performance 3D tool for Numerical Relativity.

Warp Special Relativity Simulator - A windows program to show you the weird effects of special relativity.
