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


        speedmine [-display host:display.screen] [-root]  [-window]  [-install]
        [-noinstall]  [-visual  visual]  [-wire] [-nowire] [-worm] [-foreground
        color] [-background color]  [-darkground  color]  [-lightground  color]
        [-tunnelend  color]  [-delay  microseconds] [-maxspeed number] [-thrust

                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


        -display host:display.screen
                Specifies which X display we should use (see the  section  DIS-
                PLAY 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
        -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 draw-
                ing 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 indi-
                cate  a  forwards thrust, negative numbers indicate a backwards
        -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 curva-
                ture and windiness of the tunnel or worm.
                Continuously generate a fractal terrain to simulate the  rocki-
                ness 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
        -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
                Specifies  that  the  generated  tunnel  (or  worm) may vary in
                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 ren-
                dering style.
                Indicates that bonuses should not be included in the demo.
                Specifies that a gaming style crosshair be drawn on the simula-
                tion. 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.

        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.
