cwaves — languid sinusoidal colors


cwaves [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-delay usecs] [-waves int] [-colors int] [-fps]


The cwaves program draws a languidly-scrolling vertical field of sinusoidal colors.


cwaves accepts the following options:

Draw on a newly-created window. This is the default.
Draw on the root window.
If on a color display, pretend we're on a monochrome display.
Install a private colormap for the window.
-visual visual
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.
-delay microseconds
How much of a delay should be introduced between steps of the animation. Default 20000, or about 1/50th second.
-waves int
How many cosines to add together. The more waves, the more complex the apparent motion.
-colors int
How many colors to use. Default 800. The more colors, the smoother the blending will be.
Display the current frame rate and CPU load.
