a2b is an abstract train game where you guide trains to their destination without letting them collide with each other. Each game is played on a set of tracks on which trains run at regular intervals. You pick a train and accelerate, brake, or stop as necessary to safely guide it to its destination. Since trains are continously being launched, more than 1 train will want to use the same section of a track, potentially leading to a collision. You must resolve this by making a train wait while you rush another train. As a last resort, you can send a train back to its base.
X-Plane is a flight simulator that reads in the geometric shape of any aircraft and then figures out how that aircraft will fly. It does this via an engineering process called "blade element theory", which involves breaking the aircraft down into many small elements and then finding the forces on each little element many times per second. These forces are then converted into accelerations, which are then integrated to velocities and positions. This gives X-Plane the most realistic flight model available for personal computers.
Crogai is a mix of crowd simulation, artificial intelligence, and genetic algorithms. It is possible to set up simulations and test different AI in a full 3D environment with a small physics engine, terrain, collision handling, etc. Crogai is inspired by the OpenSteer projet and uses steering behaviors as building blocks for the AI. The agents can graze, hunt each other, and emit spores for reproduction. A genetic algorithm allows the agents to evolve, and let them decide whether to do so or not. In addition, the examples provided by the project make nice screensavers.
mobileTV is a clone of the PC/Amiga game "Mad TV". The objective of the game is to manage a TV station. Scheduling the daily program includes placing movies and commercials. An hourly newscast also requires attention, as viewers want to see the latest, most interesting (and most expensive) stories. The player can produce shows, movies, and series. mobileTV should run on most recent mobile phones.
Destiney Script's Lottery script is a Web application that helps to pick your "lucky" Powerball Lottery numbers. Random quick picks use statistical logic based on previous winning numbers to inversely weight the results for better "random" picks. The latest winning Powerball results can be imported as well.
PHP Keno Simulator is a payout ruleset simulator for the classic game Keno. You can tune the payout chart to fulfill your "house advantage" or you can just calculate for fun (predefining the correct payouts) what the odds of winning are and how much your local casino is making for its owners.
