XTACY(1)XTACY(1)1.NAMExtacy - an X11 trippy color-cycling toy
SYNOPSISxtacy [ -option ... ]
DESCRIPTIONxtacy generates trippy patterns in an X window and cycles the color
palette. Without any arguments, xtacy will open a window and display a
random effect.
OPTIONS-annoy Turn on the Zoomy Close Window thing.
-bw width
Border Width. Specifies the width of the border around your win‐
dow, in pixels.
-delay msec
Delay msec microseconds between loops.
-display displayname
Opens the xtacy window on the displayname display.
-geometry geom
Opens the xtacy window with geom geometry.
-h Print out a help message.
-lock Lock the window. When given the -lock flag, xtacy prompts you
for a key, then locks the window until the key is entered again.
There is no true security guaranteed by this option.
-mirror
Mirrors the pattern on the window
-norect
Used in conjunction with -kaleid to turn off everything but the
lines.
-number num
Used in conjunction with different effect options to specify
special qualities of the effect. See the effect options below.
-opt num
Also used like -number to feed a secondary option into xtacy-part num
Used in conjunction with -gravity to specify the number of roam‐
ing particles.
-r
-root Run xtacy in the root window.
-rillybig
Run xtacy in a really big window (1024x860).
-trell Used in conjunction with -plasma to put it in Trellace mode.
-windows n
Tell xtacy to open n windows for itself.
COLOR OPTIONS-bd color
Set the border color of the xtacy window to color.
-bg color
Set the background color of the xtacy window to color.
-mono Run with a greyscale palette.
-multi Rotates the color map on most effect modes.
-few Use only 18 colors.
-several
Use 72 colors.
-colors num
Try to use num colors.
-rand
-randomcolor
Scramble the colormap.
-perfect
Use a private colormap. This will let xtacy have perfect colors
when the cursor is in that window, but will do funky things to
the rest of the screen.
-pal num|filename
Uses predefined palette num:
0: Default RYGCBM, rotating straight.
1: Three bands (red, green, and blue), each of which can rotate
independantly.
2: Like palette 1 but in greyscale.
3: Chooses 2 random colors and interpolates between them.
4: Starts with a greyscale palette, drops in a random color and
smoothes around it.
5: Chooses 3 random colors and interpolates between them.
you can also specify a Palette File, which is just a text file
with R-G-B triples ranging from 0 to 255. A few demonstration
palette files are included in the Xtacy distribution, in the
palette directory.
EFFECT OPTIONS-bez Bouncing Bezier curves. The -number option specifies how many
curves to display.
-boxes Bouncing boxes. The -number option specifies how many boxes to
display.
-bozo Bouncing quadrilaterals (bozogons). The -number option specifies
how many bozos to display.
-circ Bouncing circles. The -number option specifies how many circles
to display.
-qix Qix. The -number option specifies how many qix lines to display.
-qix4 Four qix lines, mirrored on each other. The -number option spec‐
ifies how many qix lines to display.
-blur starts with randomly placed boxes, and then blurs the edges
between them.
-cells Tile floor, cells of rotating color. The -number option speci‐
fies how many cells on a row.
-clover
Lines rotating around a center point.
-cube A spinning wire-frame cube. You may want to push up the delay to
slow this down on a fast system.
-dcurve
plots the colors based on the distance to the curve(s)-dline plots colors based on the distance to the line(s)-dog DogPlasma mode. The -number option sets the graininess.
-field Displays e-fields between random points of random intensity. The
-number option specifies how many points to display.
-flush starts with randomly drawn boxes, and moves them towards the
center of the window
-fracrect
ever decreasing squares-within-squares
-funky Shapes spiraling down to the center point. The -number option
sets the shape:
0: A straight line.
1: A square.
2: A triangle.
-gravity
Gravity well simulator. The -part option sets the number of
roaming particles and the -number option sets the number of
wells.
-julia Julia set fractal. The -number option sets the number of itera‐
tions.
-kaleid
Kaleidascope. The -norect option turns off everything but the
lines.
-life Conway's game of life. The -number option sets the starting den‐
sity.
-lunch A reminder to go eat in the middle of the day
-mandel
Mandelbrot set fractal. The -number option sets the number of
iterations.
-max Max Headroom's background (Max not included)
-newton
Newton root fractal. The -number option sets the number of iter‐
ations.
-mixer Display swirls of colors. The -number option sets the width of
the bands.
-off Off the Air color test pattern.
-plasma
Plasma cloud. The -number option sets the graininess of the
cloud (higher is smoother) and the -trell option puts it in
Trellace mode, which started as a bug but looked neat enough to
stay.
-rose Phased sine waves
-spiral
Draw a spiral.
-star Starfield simulation. The -number option determines the number
of stars on the screen at a time.
-static
Draw static. Use -mono to get black and white static.
-swarm Draw a swarm of bees following a queen.
-taffy A modified mixer mode. The -number option sets the width of the
bands.
-tag sort of the reverse of -swarm everyone avoids the leader, and
the leader tries to tag the closest bee
-test Display the colormap.
-tunnel
Display a tunnel.
-wander
Display a squiggly line, wandering around the screen.
MOUSE BUTTONS
┌───────────────┬─────────────────────────────────────────────┐
│Button Action │ Description │
├───────────────┼─────────────────────────────────────────────┤
│Button 1 click │ Rotates the colormap one pixel, except on: │
│ │ -gravity, where it places a new particle, │
│ │ -wander, where it moves the pixel, and │
│ │ -swarm, where it moves the queen. │
├───────────────┼─────────────────────────────────────────────┤
│Button 2 click │ Resets the window and redraws the effect │
├───────────────┼─────────────────────────────────────────────┤
│Button 3 click │ Closes the window. If it's the last window, │
│ │ exits the program. If the -lock option is │
│ │ on, this brings up the keyhole window. │
