Noble Ape Simulation 0.690 is a beneficial and high-speed application which creates a detailed biological environment and a cognitive simulation. It is intended as a palette for open source cross-platform development on Windows, Mac and Linux.

The Noble Ape Simulation has been in development for more than a decade.
It features a number of autonomous simulation components including a landscape simulation, biological simulation, weather simulation, sentient creature (Noble Ape) simulation and a simple intelligent-agent scripting language (ApeScript).
Major Features:

1. In addition to the ApeScript documentation on the Noble Ape site, ApeScript was also launched through Wikipedia to allow true language scrutiny through the computer language scholars and students reading through the Wikipedia language definitions.
2. The cognitive simulation is relatively central to the hardcoded version of the Simulation and optional (on by default) in the ApeScript version of the sentient simulation. This gives some freedom in the agent simulation method used through ApeScript. Advanced ApeScript users may turn the cognitive simulation off and uses the ''brain space'' as actual memory.
3. The landscape (physics) and weather simulations are autonomous components of the Noble Ape Simulation too. The weather simulation can work in either flat or spherical environments similar to the landscape simulation.
4. The biological simulation is based on quantum mechanics. The landscape's shape (height values, surface area, slopes, angle to simulated sun) can be the source of all the biological properties of the environment. This means for any landscape, a (long term) stable biological environment can exist and include a wide variety of plants and animals in the simulated ecosystem.

AstroGrav is an astronomy software program that allows you to simulate how astronomical objects move and interact under the force of gravity. It features superb interactive 3D graphics which allow you to move around within a many-body astronomical system, while watching how it evolves with the passage of time. A wide variety of sample files are provided, including Solar System, space mission, and abstract systems, and these enable you to experiment with the astronomy software without having to enter your own data. The comprehensive editing facilities allow you to either create your own astronomical systems, or to modify existing ones, and provide you with an almost endless scope for experimentation and investigation. AstroGrav calculates how astronomical objects move according to Newtons Law of Gravitation, and displays the results as they are calculated so that you can watch the system evolve as in a movie. AstroGrav is very accurate, dynamically calculates orbits as a system evolves, deals correctly with object collisions, and can cope simultaneously with objects on many different timescales. AstroGrav is available for both Mac and Windows, comes complete with a tutorial and full documentation, and you can download a fully functional 15 day trial version for evaluation.
