breve is a simulation environment which allows users to define the behaviors and interactions of different types of agents in a simulated 3D world and observe the emergent behaviors. breve is conceptually similar to packages such as Swarm and StarLogo, but simulates objects in a continuous 3D world with continuous time.
breve thus allows simulation involving realistic collision detection and physics.
Agent behaviors are written in a simple object oriented language called "steve".
Users define an agents behavior by specifying how the agent interacts with the world at each timestep and how the agent interacts when it collides with other agents. breve includes full collision detection and experimental support for real physical simulation of rigid bodies.
Enhancements:
- Universal PPC/Intel build for Mac OS X
- New garbage collection system for improved stability and memory management
- Enhanced support for genetic algorithms and evolutionary computation.

Using Hexacolor you can mix your desired color using RGB 0-255 or RGB percentages [like the ones used in QuarkXPress] and you can easily convert RGB 0-255 values to RGB percentage values or vice versa, just by clicking the % tick box.
Hexacolor allows you to convert colors to websafe HEX colors.

Since Mac OS X 10.3, there is no identd server on the system. So Ive decided to build a standalone identd server. This server runs on Panther and Tiger and is provided with a preference pane which allows you to easily start or stop it.
This identd server returns the short username of the user which is currently logged in Aqua.
This kind of server could be useful if your Mac is behind a proxy server which requires authentication or when you use IRC.
Enhancements:
- recompiled and now run on Mac OS X 10.3.9 or higher
- tested on an Intel based iMac.
