The Second Life Viewer is the client for logging into the Second Life 3-D virtual world, where residents explore, purchase virtual land, open businesses, build real estate, and create scripted objects such as cars, robots, or magic wands. Second Life residents retain full intellectual property rights for the digital content they create and upload, including avatar characters, clothing, scripts, textures, objects, and designs.
Open DESIRE is a modeling/simulation language for dynamic systems and neural networks, a runtime compiler, and an experiment-protocol script for simulation studies. It supports up to 40,000 differential equations or neural networks, in scalar and/or vector form. It also supports very fast Monte Carlo studies and complex frequency-response plots.
pyFormex is a tool for generating, manipulating, and transforming large geometrical models of 3D structures by sequences of mathematical transformations. Thanks to a powerful (Python based) scripting language, it is very well suited for the automated design of spatial frame structures. It provides a wide range of operations on surface meshes, like STL type triangulated surfaces. There are provisions to import medical scan images. pyFormex can also be used as a pre- and post-processor for Finite Element analysis programs. Finally, it might be used just for creating some nice graphics.
cave9 is a gravity cave-exploration game. It's a first person 3D version of the classic SF-Cave game. Your ship travels into a procedurally-generated cave at constant forward speed, and you have to control two diagonal thrusts to keep it from hitting the walls. As the game progress, the cave will twist more and become more tight.
