       speedmine - simulates speeding down a rocky mineshaft, or a funky dancing worm

               Down the speedmine, you'll find speed

               to satisfy your moving needs;

               So if you're looking for a blast

               then hit the speedmine, really fast.

       Speedworm loves you.

       Speedworm likes to bump and grind

       and chase her tail, and dance around

       she really is a funky friend;

       she's made of speed from end to end.

       You can configure stuff either with command-line options or X resources.


       -display host:display.screen
               Specifies which X display we should use (see the section DISPLAY NAMES in X(1) for
               more information about this option).

       -root   Draw on the root window.

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

               Install a private colormap for the window.

               Don't 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.  Possible choices include

               default,  best,  mono,  monochrome,  gray,  grey,  color, staticgray, staticcolor,
               truecolor, grayscale, greyscale, pseudocolor, directcolor, number

               If a decimal or hexadecimal number is used,  XGetVisualInfo(3X)  is  consulted  to
               obtain the required visual.

       -worm   Be a happy spastic worm instead of a tunnel.

       -wire   Specifies that the tunnel/worm should always be rendered in wireframe style.

       -nowire Specifies  that  the  tunnel/worm  should  be  rendered normally. Note that tunnel
               rendering may still temporarily switch to wireframe style when a  wireframe  bonus
               is hit, if bonuses are enabled.

       -foreground color
               Specifies the default foreground color.

       -background color
               Specifies the default background color.

       -darkground color
               Specifies  the  color of the darkest portions of the ground (or the worm's belly.)
               The ground/belly is colored by a gradient between darkground and lightground.

       -lightground color
               Specifies  the  color  of  the  lightest  portions  of  the   ground/belly.    The
               ground/belly is colored by a gradient between darkground and lightground.

       -tunnelend color
               Specifies the color of the light at the end of the tunnel.

       -delay microseconds
               Specifies  the  delay  between  drawing  successive  frames. If you do not specify
               -sync, some X servers may batch up several drawing operations together,  producing
               a  less  smooth  effect.    This  is  more likely to happen in monochrome mode (on
               monochrome servers or when -mono is specified).

       -maxspeed number
               Specifies an upper bound on the speed of normal movement. This does not affect the
               speed that may be attained when hitting a speed bonus.

       -thrust number
               Specifies  the  thrust  constantly  applied.  Positive numbers indicate a forwards
               thrust, negative numbers indicate a backwards thrust.

       -gravity number
               Specifies the  effect  of  gravity.  Larger  numbers  will  increase  acceleration
               downhill and decrease acceleration uphill.

       -vertigo number
               Specifies  to what level the demo should accentuate the curvature and windiness of
               the tunnel or worm.

               Continuously generate a fractal terrain to simulate the rockiness  of  the  tunnel
               walls, or the texture of the worm's skin.

               Do not generate terrain. When this option is set, all surfaces are flat.

       -smoothness number
               When -terrain is set, specifies how smooth the walls or skin are.

       -curviness number
               Controls  how much the generated tunnel (or worm) should curve left and right, and
               dip up and down.

       -twistiness number
               Controls how much the generated tunnel (or worm) twists around itself.

               Specifies that the generated tunnel (or worm) may vary in width.

               Specifies that the average width should be kept constant.

       -bumps  Indicates that the simulation should take the bumpiness of the ground into account
               and allow the animation to shake and rattle when travelling over rough ground.  Or
               that the worm should be allowed to bump around and shake her booty.

               Indicates that the bumpiness of the  ground  should  be  ignored,  such  that  the
               simulation  will  glide through the tunnel.  Or that the worm should calm down and
               behave herself.

               Indicates that the demo should include bonus events. These include speed  bonuses,
               spins, and changes of viewpoint and rendering style.

               Indicates that bonuses should not be included in the demo.

               Specifies  that  a  gaming style crosshair be drawn on the simulation. This serves
               little purpose but may make hardcore gamers feel more comfortable.

               Specifies that no crosshair be drawn.

               Specifies that a psychedelic colormap should be generated. When this is  set,  the
               walls and ground of the tunnel are drawn in an often changing rainbow of colours.

               Specifies that a normal colormap should be used, with muted walls and a grey road.

       -fps    Display the current frame rate and CPU load.

       Prolonged  viewing  of  this  demo  with  maxspeed and vertigo above the defaults may have
       short-term psychological side effects including hyperactivity and attention deficiency.
