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.
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.
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, true-
color, 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 ren-
dering may still temporarily switch to wireframe style when a wireframe bonus is
hit, if bonuses are enabled.
Specifies the default foreground color.
Specifies the default background 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.
Specifies the color of the lightest portions of the ground/belly. The
ground/belly is colored by a gradient between darkground and lightground.
Specifies the color of the light at the end of the tunnel.
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 mono-
chrome servers or when -mono is specified).
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.
Specifies the thrust constantly applied. Positive numbers indicate a forwards
thrust, negative numbers indicate a backwards thrust.
Specifies the effect of gravity. Larger numbers will increase acceleration down-
hill and decrease acceleration uphill.
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.
When -terrain is set, specifies how smooth the walls or skin are.
Controls how much the generated tunnel (or worm) should curve left and right, and
dip up and down.
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 simu-
lation will glide through the tunnel. Or that the worm should calm down and
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.

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.
