This is my favorite screen saver in all the world.

Normally I hate screen savers, I really do. If the point is to save
the screen from burn-in (which doesn't happen these days), they're
silly. If the point is to occupy my attention, I have a host of better
ideas. If the point is to be pretty, they usually fail.

Except ElectroPaint. Which is something that came with SGI machines,
and I presume it still does. It was strange and hypnotic and I could
stare at it for hours. Once I set it running on twelve machines in the
same room and turned the lights off. That was pretty good.

Unfortunately and dammit, the source code to ElectroPaint has never
been released, and it only runs on SGI machines. This bugged me for
years. So I finally got off my butt and reimplemented it for the
Macintosh.

(Actually, the first thing I did was to reimplement it in sound.
That's StonerSound, for which see my web pages. But I made it back
into a visual toy after that.)

Please note that this contains no code from ElectroPaint. I've never
seen any. StonerView is entirely my own code, inspired only by my
memory of what ElectroPaint looked like. (In fact, when I wrote this,
I hadn't seen ElectroPaint run for over a year.)

StonerView originally used QuickDraw 3D for its display system. Since
not even Apple gives a toss about QD3D any more, I've done this quick
port to GL. It just pops up an X window with the goods running
therein. (I used glut for this, because that's what I had example code
for.)

(Wouldn't it be nice if you could make it run in the root window? So
that it would really work as a screen saver? Yes, it would. Wouldn't
it be nice if I had some documentation for glut, so that I could
implement that? Yeah, that too. "Maybe next version." I tried looking
at the GL samples in the xscreensaver distribution... for some reason,
it didn't help.)

If you find that StonerView is running too slowly, reduce the window
size.

Version history:

1.5.2 (MacOSX port): Updates to build / run on MacOS X 11 (BigSur) and
                     M1 Macs

1.5 (MacOSX universal binary port): contributed by Alexander v. Below

1.4 (MacOSX port): contributed by Tommaso Pecorella

1.3: Jamie Zawinski ([email protected]) contributed a pile of code to change 
     the framework from GLUT to straight GL. This allows the --root 
     option to work, and therefore it works with the xscreensaver
     package.

1.2: I forgot the sliding rainbow effect on the chain of polygons!
     Can you believe that? I'm such a doof.
     Also, Unix/GL version.

1.1: Original release, I think.
