XBattleAI is an enhanced version of the Unix strategy game XBattle. XBattleAI is an elegant and abstract realtime strategy game for multiple players or a single player. It is based on the last stable version of XBattle (5.4.1), and adds the option of using computer-controlled opponents, campaigns, some bugfixes, and some miscellaneous extra features.
Spana/Panorama is a protocol and a reference implementation for a new peer-to-peer network with the primary goals of providing anonymity and a robust network. Some of the implemented features are: anonymous file transfers (on both ends) and news (NNTP), RSA-based virtual identities for file authentication, advanced file indexing for searching (such as on bit rates), and automatically resumed downloads from multiple hosts using cryptographically strong checksums on files (cf. heuristics based on filenames) for security and flexibility.
Trackballs is a simple game similar to the classic game Marble Madness. By steering a marble through a track filled with vicious hammers, pools of acid, and other obstacles the player collects points. When the ball reaches the destination, the player continue to the next, more difficult track - unless, of course, time runs out first.
X-grav is a simple physics simulation for a large number of particles. It simulates the effect of gravity, collisions, heat dissipation, and a simple chemical reaction. The simulation is in no way meant to be realistic but rather a toy with which you can create stars, planets, and even simple solar systems.
Galapagos is a fairly detail artificial life project in which a number of creatures are simulated over time. The simulation follows a number of laws which are inspired by, although not replicating, the standard laws of nature. By implementing mutations and crossovers and the implicit natural selection in the simulation, the overall result is an evolution of the creatures in which new breeds of creatures fullfilling different ecological niches arise.
