XRazzle! An XScreenSaver Hack

hacked by Bradley Bell

Intro

XRazzle draws animated, color-cycling, abstract, random-line stereograms (the kind you have to cross your eyes to see). Have a look at the screenshots, and imagine the designs and colors constantly changing. No, you won't see a dinosaur or a boat or anything like that, they're completely abstract.

Installation

This program requires XScreenSaver to compile, please read the documentation provided with XScreenSaver.
Download and unpack the latest XScreenSaver
Place xrazzle.c from the latest XRazzle source into the hacks/ directory ofthe XScreenSaver source, and add the necessary lines to hacks/Makefile.in (this means add xrazzle.c to SRCS, xrazzle.o to OBJS, xrazzle to EXES, and add the following two lines to the rules section or whatever it's called.)
```
xrazzle: $(HACK_OBJS) xrazzle.o $(COL)
	$(CC_HACK) -o $@ $(HACK_OBJS) xrazzle.o $(COL) $(HACK_LIBS)
	
```
Run configure and make as usual.
Don't forget to add XRazzle to your XScreenSaver*programs resource. (e.g. xrazzle -root)

XRazzle accepts the following options as X resources or command-line options:

drawFunc	The drawing function to use, numbered 1 to 38 -- You'll have to look at the source code to see what they are. Default value is 0, which makes it pick one at random.
paletteType	Type of palette fill to use. 1=smooth, 2=uniform, 3=random, 4=open ramp, 5=closed ramp, 6=loop Defaults to 0, which will pick one at random.
nColors	Number of colors to use, from 64 to 256. Default is 256.
nMax	Number of iterations to make before switching to the next drawing function. Default is 1000.
delay	Time in microseconds to delay between frames. Default is 500.
cycle	Cycle colors The same as X resource *cycle: True
no-cycle	Do not cycle colors (default) The same as X resource *cycle: False
nCycle	Number of iterations to wait before cycle. Default is 5.
hCells	Numbers of cells to display horizontally. Defaults to 0, which picks a random number between 4 and 8.
vCells	Numbers of cells to display vertically. Defaults to 0, which picks a random number between 1 and 7.
