DESCRIPTION

       Speedmine!

               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.

OPTIONS

       --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-id number
               Draw on the specified window.

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

       --install
               Install a private colormap for the window.

       --noinstall
               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.

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

       -noterrain
               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.

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

       -nowidening
               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.

       -nobumps
               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.

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

       -nobonuses
               Indicates that bonuses should not be included in the demo.

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

       -nocrosshair
               Specifies that no crosshair be drawn.

       -psychedelic
               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.

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

       --fps   Display the current frame rate and CPU load.

WARNING

       Speedworm is a trained professional. Do not try this at home.

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

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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
