The xscreensaver program waits until the keyboard and mouse have been idle
for a period, and then runs a graphics demo chosen at random. It turns off
installed: you don't need to recompile this program to add a new display
mode, you just change some resource settings. Any program which can be
invoked in such a way that it draws on the root window of the screen can
-now be used as a screensaver without modification [*]. The programs that
+now be used as a screensaver without modification. The programs that
are being run as screensavers don't need to have any special knowledge
about what it means to be a screensaver.
-The XIdle extension will be used if you have it (win win.)
+The XIDLE or MIT-SCREEN-SAVER server extensions will be used if you have them.
Unfortunately, locking doesn't work if you don't have Motif.
qix - My own implementation of this, with many more options
than you would have thought qix could have.
helix - Generates spirally "stringart" patterns.
+ pedal - Draws a different kind of spirally pattern.
rorschach - Random inkblot patterns.
attraction - A bouncing ball demo, or a qix-like demo, or a wild
color-cycling thing, with some odd rules.
imsmap - Generates random maps or cloud formations.
hypercube - 2d projection of a hypercube rotating on all four axes.
slidescreen - Divides the screen into a grid and plays a 16-puzzle on it.
+ decayscreen - A melting effect.
halo - Random circular patterns.
pyro - Fireworks. Looks a lot like the version in xlock.
hopalong - Fractals. I snarfed this code from xlock.
+ flame - Fractals. Also from xlock.
noseguy - A guy with a big nose wanders around the screen saying
things. I snarfed this code from xnlock.
maze - This is the X maze demo modified to take a -root option
so that it works with xscreensaver.
+ lmorph - morphing line drawings.
All of these will pop up their own window unless given that -root option.
See their man pages for more details.
kaleid -root - qix-like kaleidescope patterns
xfishtank -c black -d -r 1 - fish (use version 2.0 or later)
-You can get all of these from export.lcs.mit.edu. If you know of (or write)
-any other interesting programs that can be used as screensavers, please let

+ than using the RNG in libc.
+ Made locking work on SCO.
+ Various other minor tweaks that I don't remember.
+Changes since 1.24: Made it capture the stdout/stderr of its subprocesses
+ and present them on the screensaver window itself.

+ Support for the R6 MIT-SCREEN-SAVER server extension.
+ Made the demo mode list scroll properly.
+ Added `pedal' hack.
+Changes since 1.23: Fixed some private-colormap oddities in slidescreen,
+ decayscreen, and xroger. Fixed apparent conservation-
+ of-mass problem in pyro; made the shrapnel round.

+Changes since 1.14: Broke the driver up into more source files.
+ Moved the hacks into their own directory.
+ Made all `time' parameters accept the 00:00:00 syntax,
+ so that even the parameters which are normally read as
+ `minutes' can be specified in seconds.
+ Added colormap cycling to `imsmap'.
+ Made hyper work with K&R compilers.
+Changes since 1.13: Added `orbit' option to `attraction' hack.
