============
The xscreensaver program waits until the keyboard and mouse have been idle
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.
+ puzzle - Turns the screen into a jigsaw puzzle and shuffles it.
halo - Random circular patterns.
pyro - Fireworks. Looks a lot like the version in xlock.
hopalong - Fractals. I snarfed this code from xlock.
bouboule - Spinning bubbles on a transparent ball.
braid - Draws random color-cycling braids around a circle.
drift - Drifting recursive fractal cosmic flames.
- fract - Small, curvy geometric patterns.
+ vines - Small, curvy geometric patterns.
galaxy - Spinning, colliding galaxies.
grav - Orbital simulation and/or cloud chamber.
ifs - Spinning, colliding iterated-function-system shapes.
spiral - Circular color-cycling interference patterns.
strange - Animating strange attractors.
flag - A waving flag of an arbitrary bitmap or text.
- sphere - draw a bunch of shaded spheres.
+ sphere - Draws a bunch of shaded spheres.
forest - grows a fractal forest.
lisa - draws animated full-loop lisajous figures.
+ lissie - another lisajous path.
goop - Squishy transparent oil-and-bubble images
starfish - Radially-symmetric throbbing colormap-hacking blobs.
munch - The classic 1962-vintage "munching squares" hack.
rd-bomb - Reaction-diffusion fractals.
coral - Simulation of coral growth, sort of.
fadeplot - Draws a swimming ribbon.
+ mountain - Generates mountains on a square grid.
+ triangle - Generates mountains on a triangular grid.
+ worm - Draws wiggly worms.
+ rotor - Draws a rotating spiral pattern.
+ ant - A cellular automaton.
+ xjack - Simulates a schizophrenic typist.
+ xlyap - Calculates and displays Lyapunov exponents.
escher - Draws some escher-like scenes (GLX only.)
gears - Draws interlocking rotating gears (GLX only.)
morph3d - Draws shiny shape-changing 3d forms (GLX only.)
xv -root file.gif -quit - they don't all have to animate!
xsplinefun - bouncing splines
xfishtank -c black -d -r 1 - fish (use version 2.0 or later)
+ xmountains -b - very realistic generated mountains
xtacy -root - various eye candy
- /usr/demos/bin/bongo -wbongo - an SGI GL demo
+ xearth -wait 0 -timewarp 400 - the earth as seen from space
+ /usr/demos/bin/bongo - an SGI GL demo
+ /usr/demos/bin/ep -S - another: the stunning ElectroPaint.
+ (Compile hacks/xscreensaver-sgigl.c
+ to use these with xscreensaver.)

-Changes since 2.09: Fixed color bugs in rd-bomb; sped up coral.
-Changes since 2.07: New hacks "rd-bomb" and "coral".
- New version of "maze" with some new algorithms.
- New colorized version of "rocks".
+Changes since 2.13: Better fix for the Motif drag-and-die lossage.
+ Put in some kludges to work around a LessTif bug.
+ XScreenSaver is known to work with LessTif 0.82 now.
+ Made fading work on high-end SGI video hardware.
+ Fixed another SGI-specific bug in screen grabbing;
+ will the madness never cease?
+ Fixed another crash in `xlyap'.
+Changes since 2.12: Made `decayscreen' do directions other than down.
+ Improved `puzzle'.
+ Fixed a crash in `xlyap'.
+ Added CDE info to the man page, removed `cde.txt'.
+ Configure tweaks for Zippy.
+ Turned off the signal handling in `bubbles' because
+ it was sometimes failing to die.
+ Added `hacks/xscreensaver-sgigl.c' to make it possible
+ to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
+ with xscreensaver. Finally!
+ Fixed a buffer overrun in the locking code that some
+ wily, malicious cracker must have slipped in.
+ Disabled Motif drag-and-drool in the dialog box
+ buttons, since it's broken in some old versions of
+ Motif.
+Changes since 2.11: Added `README.debugging'.
+ Added `puzzle' hack.
+ Added `xlyap' hack.
+ Added "default-n" as a visual name, so that one can
+ have -install on by default, but turn it off for
+ certain poorly-behaved hacks (like xv.)
+ Added support for grabbing frames of external video
+ (on SGI) to the screen-grabbing hacks (decayscreen,
+ slidescreen, slip, blitspin, and puzzle.)
+ Improved look of tiles in `slidescreen'; fixed its
+ color allocation problem.
+Changes since 2.10: Tweaked `blitspin', added it to the default list.
+ Added `lissie', `mountain', `triangle', `worm',
+ `rotor', and `ant' from xlockmore.
+ Updated `sierpinski', `galaxy', and `lisa'.
+ Thickened the lines in `braid' and `lmorph'.
+ Updated VMS makefiles.
+ Renamed `fract' to `vines'.
+ Added `xjack' hack.
+ Made a few more hacks use erase.c, and added a few
+ more wipe styles.
+ Fixed compilation problem with Sun's version of OpenGL.
+ Added ability to use sigaction() instead of signal()
+ to work around a SCO kernel bug.
+Changes since 2.09: Fixed colormap bugs in `rd-bomb'; sped up `coral'.
+ Configure tweaks for *BSD.
+Changes since 2.07: New hacks `rd-bomb' and `coral'.
+ New version of `maze' with some new algorithms.
+ New colorized version of `rocks'.
Fixed a bug in qix on 64-bit machines.
Fixed a bug in the -time option.
Fixed a bug in configure related to LessTif.
