DESCRIPTION

       The goal of nerverot is to be interesting and compelling to watch, yet induce a state of nervous  edginess  in  the  viewer.  This  manpage
       describes v1.3 of the program.

OPTIONS

       nerverot accepts the following options:

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

       -mono   If on a color display, pretend we're on a monochrome display.

       -install
	       Install a private colormap for the window.

       -visual visual
	       Which visual to use.  Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.

       -db     -no-db  Use  double-buffering  (or  not,  respectively). Double-buffering may make things look better for larger line widths and/or
	       larger numbers of blots, but "better" may equate to yielding less of the desired edginess effect. You'll be calmer  after  watching
	       the  double-buffered  variant;  you're  more  likely  to  go  into epileptic fits with it off. Hence, it is off (false) by default,
	       resource doubleBuffer.

       -colors integer
	       How many colors should be used (if possible). The colors form a smooth ramp between two	randomly-chosen  colors.  Defaults  to	4,
	       resource colors.

       -delay microseconds
	       The interframe delay, in microseconds. Defaults to 10000, resource delay.

       -max-iters integer
	       The  maximum  number  of iterations (frames) before a new model is generated. The actual number of iterations per model is a random
	       number between 1 and this value. Defaults to 1200, resource maxIters.

       -count integer
	       How many "blots" to draw at a time. This number may be rounded down to fit the particularly chosen model, and has a  fixed  minimum
	       per-model.  Defaults to 250, resource count.

       -line-width integer
	       The width of the lines to draw. 0 means an optimized pixel-thick line.  Defaults to 0, resource lineWidth.

       -event-chance fraction
	       The  chance, per iteration, for a life-altering event to occur (such as picking a new rotation target), in the range 0..1. Defaults
	       to 0.2, resource eventChance.

       -iter-amt fraction
	       The fraction of movement towards a target (such as rotation angle or scale) that happens per iteration, in the range 0..1. Defaults
	       to 0.01, resource iterAmt.

       -nervousness fraction
	       How  nervous  the  drawing is, in the range 0..1. This is how jumpy the points on each blot are. Defaults to 0.3, resource nervous-
	       ness.

       -max-nerve-radius fraction
	       The maximum radius of blot nervousness, as a fraction of the radius of the blot, in the range 0..1. Defaults to 0.7, resource maxN-
	       erveRadius.

       -min-radius integer
	       The minimum radius for a blot, in the range 1..100. Defaults to 3, resource minRadius.

       -max-radius integer
	       The maximum radius for a blot, in the range 1..100. Defaults to 25, resource maxRadius.

       -min-scale fraction
	       The minimum overall scale of drawing, as a fraction of min(windowHeight,windowWidth), in the range 0..10. Defaults to 0.6, resource
	       minScale.

       -max-scale fraction
	       The maximum overall scale of drawing, as a fraction of  min(windowHeight,windowWidth),  in  the	range  0..10.  Defaults  to  1.75,
	       resource maxScale.

       -fps    Display the current frame rate and CPU load.

ENVIRONMENT

       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.

X RESOURCES

       There are resource equivalents for each option, noted above.

BUGS

       nerverot should have more models.

       XDBE should be detected and used, if available.
