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.
