       nerverot - induces edginess in the viewer

       nerverot  [-display  host:display.screen]  [-foreground  color] [-back-
       ground color] [-window] [-root]  [-mono]  [-install]  [-visual  visual]
       [-db] [-no-db] [-colors integer] [-delay microseconds] [-count integer]
       [-line-width integer]  [-event-chance  fraction]  [-iter-amt  fraction]
       [-nervousness fraction] [-max-nerve-radius fraction] [-min-radius inte-
       ger] [-max-radius integer] [-min-scale fraction] [-max-scale fraction]

       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.

       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 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 ran-
               dom number between 1 and this value. Defaults to 1200, resource

       -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 min-
               imum 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

       -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 maxNerveRadius.

       -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(win-
               dowHeight,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(win-
               dowHeight,windowWidth),  in  the range 0..10. Defaults to 1.75,
               resource maxScale.

       DISPLAY 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.

       There are resource equivalents for each option, noted above.

       nerverot should have more models.

       XDBE should be detected and used, if available.
