Manic Digger - Open Source Sandbox Game - PC

Manic Digger is an open-source implementation of block-building games as made famous by Minecraft. Manic Digger started as a third-party client for Minecraft Classic but that compatibility was removed. Manic Digger is a free sandbox game in which you build using square blocks made of varying elements and materials. You can build anything you can imagine using the default blocks Manic Digger offers.

A Slower Speed of Light

A Slower Speed of Light is a first-person game prototype in which players navigate a 3D space while picking up orbs that reduce the speed of light in increments. Custom-built, open-source relativistic graphics code allows the speed of light in the game to approach the player's own maximum walking speed. Visual effects of special relativity gradually become apparent to the player, increasing the challenge of gameplay. These effects, rendered in realtime to vertex accuracy, include the Doppler effect (red- and blue-shifting of visible light, and the shifting of infrared and ultraviolet light into the visible spectrum); the searchlight effect (increased brightness in the direction of travel); time dilation (differences in the perceived passage of time from the player and the outside world); Lorentz transformation (warping of space at near-light speeds); and the runtime effect (the ability to see objects as they were in the past, due to the travel time of light). Players can choose to share their mastery and experience of the game through Twitter. A Slower Speed of Light combines accessible gameplay and a fantasy setting with theoretical and computational physics research to deliver an engaging and pedagogically rich experience.

OpenTyrian & Tyrian 2000

OpenTyrian is a port of the DOS shoot-em-up Tyrian. Jason Emery generously gave the OpenTyrian developers a copy of the Tyrian 2.1 source code, which has since been ported from Turbo Pascal to C. The port uses SDL, making it easily cross-platform.


Tyrian is an arcade-style vertical scrolling shooter. The story is set in 20,031 where you play as Trent Hawkins, a skilled fighter-pilot employed to fight Microsol and save the galaxy.
