ChemicalBurn. By Michael Ash DownloadDownload ChemicalBurn (104K) Requires Mac OS X 10.4 or later. ChemicalBurn is a screensaver that simulates a transportation network. Packages are generated with a destination, and attempt to find the fastest way there. Frequently used routes get faster, making them more popular.
The result is a beautiful self-organizing network colorfully displayed on your screen. ChemicalBurn is open source. New in 1.1.4:• Fixed large memory leaks when running in 64-bit mode. New in 1.1.3:• Full compatibility with Mac OS X 10.6 Snow Leopard. New in 1.1.2:• Fixed two bugs which could cause the routing algorithm to fail, freezing or crashing the screensaver. New in 1.1.1:• Fixed deadlock in threading code, added watchdog thread to terminate gracefully in case of other deadlocks.
New in 1.1:• ChemicalBurn is now multithreaded to take advantage of multicore and multiprocessor Macintoshes. How it WorksNodes are randomly generated on the screen.

Ready for Prime Time: Open Source Programs for the K-12 Desktop: This week I moderated a CoSN webcast on Free and Open Source Software (FOSS) with guests Laura Taylor (the director of the Office of Learning Resources at the Indiana Department of Education) and Jim Klein (the director of Information Services & Technology at Saugus Union School District in California).
Below is a starter list of FOSS programs we came up with for the K-12 desktop that you can start using in the classroom right away–and that can be given to students for free. Au is a free, easy-to-use audio editor and recorder for Windows, Mac OS X, GNU/Linux, and other operating systems. You can use Audacity to: Record live audio Convert tapes and records into digital recordings or CDs Edit Ogg Vorbis, MP3, and WAV sound files Cut, copy, splice, and mix sounds together Change the speed or pitch of a recording And more! Vex - A Visual Editor for XML. ParaView. VisIt. VisIt is an Open Source, interactive, scalable, visualization, animation and analysis tool. From Unix, Windows or Mac workstations, users can interactively visualize and analyze data ranging in scale from small (<101 core) desktop-sized projects to large (>105 core) leadership-class computing facility simulation campaigns.
Users can quickly generate visualizations, animate them through time, manipulate them with a variety of operators and mathematical expressions, and save the resulting images and animations for presentations. VisIt contains a rich set of visualization features to enable users to view a wide variety of data including scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured, adaptive and unstructured meshes. Owing to its customizeable plugin design, VisIt is capabable of visualizing data from over 120 different scientific data formats (see this partial list). See the table below for more details about the tool’s features. History Key Features. Richard Stallman.
