Sandbox provides facilities for learning and experimenting with Python, and for creating and editing Python files. It is designed to be easy to learn and use, and to provide a PyQt-based alternative to IDLE. (
breve is a free, open-source software package which makes it easy to build 3D simulations of multi-agent systems and artificial life. Users define the behaviors of agents in a 3D world and observe how they interact. Agents behaviors can be written in Python, or using a simple scripting language called “steve”. breve includes physical simulation and collision detection so you can simulate realistic creatures, and an OpenGL display engine so you can visualize your simulated worlds.
breve is available for Mac OS X, Linux and Windows
Erik Thompson has a very nice video showing how you can use VPython to simulate a ball falling under the effects of gravity. it’s reasonably simple. It could be used to show how computers can simulate the physical world.
World Wind lets you zoom from satellite altitude into any place on Earth. Leveraging Landsat satellite imagery and Shuttle Radar Topography Mission data, World Wind lets you experience Earth terrain in visually rich 3D, just as if you were really there.
Virtually visit any place in the world. Look across the Andes, into the Grand Canyon, over the Alps, or along the African Sahara.
A really good example of computers and graphics.
Some good ideas for exercises to teach HTML and CSS.
