"Mek is mechanics simulation software. You input some particles, give their initial positions, velocities, masses, electric charges. You specify external fields. Trajectories are computed in real time, you can zoom in and out, speed up or slow down the simulation. Force and velocity vectors can be output to be used inside a spreadsheet or gnuplot...."
"Lum is a simulator for centered optic systems. You put optical devices on an axis, then you can request drawing of distinguished light beams to find the image of an object. You can bind a bitmap image to an object, and see its projection on the screen...."
"geg is capable of drawing 2-dimensional mathematical functions within a nice user interface. e.g., f(x) = 3 + sin(x/2). geg allows you to view multiple functions simultaneously, with each function drawn in a different color. Functions can be selectively erased and are easily identifiable by colour matching. The viewport can be zoomed in and out, and can zoom in on selected regions."
