Mass and spring simulation system

XSpringies is a mass and spring simulation system. It’s intended use is more like that of a game, than some design package.

It’s written using Xlib only. No Motif or any other widgets sets are used.

The animation in XSpringies is done using an off-screen Pixmap. The next frame is drawn on this pixmap, then is blitted onto the screen. Since the frame rate is about 30 frames per second, slower machines or machines which have poorly written bit-blitting code will be deathly slow and blinky.
