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 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 wire
frame 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 num
bers 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 simu
late 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 rain
bow of colours. - -nopsychedelic
- Specifies that a normal colormap should be used,
with muted walls and a grey road.

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.
