The Bubbling Load Monitor (or "Bubblemon" for short) is a system load monitor for the GNOME panel. It looks like a vial containing water. The water level indicates how much (electronic) memory is in use. The color of the liquid indicates how much swap space is used. The amount of bubbles reflects the system CPU load. A message in a bottle indicates there is unread mail. A reed-like graph shows I/O load. On multi-core systems the CPU with the highest load will bubble in the middle, and the others on the sides, so it's possible to see how well load gets distributed between CPUs.
Genius is an arbitrary precision integer and multiple precision floating point calculator. It includes its own programming language similar in some aspects to C, bc, or Pascal. It can deal with rational numbers and complex numbers. It has matrix support as well. It uses the gmp library so it is very fast for calculations of large numbers. It has a command line and a GNOME interface. The GNOME interface supports plotting functions and 3D surfaces.
KMatplot is an Origin-like tool for plotting data sets in either two or three dimensions. It can plot many ordinary types of 2D plots, including pixmaps, contours, and 3D surfaces. It offers a full WYSIWYG mode with many graphs on a single page and a simple command interface for Octave and Scilab.
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.
RobotFlow is a mobile robotics tookit based on the FlowDesigner project. FlowDesigner is a data-flow oriented architecture, similar to Simulink (Matlab) or Labview that is free and versatile. The visual programming interface provided in the FlowDesigner project will help people to better visualize & understand what is really happening in the robot's control loops, sensors, actuators, by using graphical probes and debugging in real-time.
Qt/Grass is a C++ library that makes it easy to create applications using the GRASS GIS system and Qt. It supports layering with a dialog that can control the color attributes of each layer and ordering, rendering of all GRASS 2-D formats (raster, vector, site) on any Qt painter, Interactive zoom, pan, xy-to-lat- long, and distance-x1-y1-x2-y2.
libbubblemon is a library for making bubbling meters like the original bubbling load monitor. The library accepts numbers as input for the different visualizations (water-level, color, amount of bubbles, amount of growth from the bottom, and whether something is floating in the water). It then renders a picture of it that the caller is responsible for passing to the screen. As long as you render an image at least 10 times per second, the animation will be smooth.
