pinion - draws a scrolling sequence of interconnected gears

pinion [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay usecs] [-scroll ratio] [-spin ratio] [-size ratio] [-max-rpm int] [-wireframe] [-fps]

The pinion program draws an interconnected set of gears moving across the screen.

pinion accepts the following options:

Draw on a newly-created window. This is the default.
Draw on the root window.
Install a private colormap for the window.
Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.
The delay between frames of the animation, in microseconds: default 15000.
How fast the gears should spin; default 1.0. 2.0 means twice as fast, 0.5 means half as fast.
How fast the gears should scroll past the screen; default 1.0. 2.0 means twice as fast, 0.5 means half as fast.
How big the gears should be, on average; default 1.0. 2.0 means twice as large, 0.5 means half as large.
If any gear exceeds the maximum RPM, the current gear train is broken there, and we start a new train. Default: 900 RPM. (At 30 FPS, that's about half a rotation per frame.)
Render in wireframe instead of solid.
Display the current frame rate, CPU load, and polygon count.

to get the default host and display number.
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
