Snow Path Formation Simulator is a program that models the process of people forming very distinct, and yet not always altogether logical looking, paths in the snow as they walk across open spaces. The evolving condition of the snow is displayed graphically. This project may eventually mature into a screensaver.
Mage is a 3D vector display program that shows "kinemage" graphics used in both teaching and research, in applications ranging from estuary ecology to X-ray crystallography model quality assessments. It displays the 3D relationships between data in an interactive environment, which facilitates both open-ended exploration and structured presentation. It includes many tools for on-screen measurement, construction, and editing of the display objects, and can write either kinemage output or various types of 2D images.
humanzip is a compression program that operates on text files. Unlike most compression algorithms, its output is human readable. Indeed, it is explicitly meant to be read by humans and might even be easier to read than the original. humanzip compresses files by looking for common strings of words and replacing them with single symbols. The idea is to reduce the screen and print size of documents. humanzip does not explicitly try to reduce the size of the file as measured in bytes, although this usually happens incidentally.
Re: Other uses?
To simulate forming dirt paths in grass, set -impact to about .9999 and maybe set -lengthweight higher, since the difficulty of walking through grass is generally lower than that of walking through snow. And set -cycles to something very high or 0 (unlimited), cause otherwise you'll never see a difference.
snowpath -impact .9999 -cycles 0 -lengthweight 200
And if you're really hardcore, modify the source so that it fades from green to brown instead of white to black.
Re: compiling in/for Linux 2.6
Never mind, it works now.
