Brief - "Gallery One" is a menu-based presentation
of graphic animation on the Rainbow under a
high-level language. The demo is restricted
to medium-level resolution and does not take
advantage of all the graphics system's cap-
abilites. It is for demo purposes only!

DESCRIPTION -
"Gallery One" was created from discoveries made on the road
towards discovering other things. In "Gallery One", a basic geo-
metrical shape, the square, was put into motion; rotated, manipu-
lated, sped up and slowed down. When interacting this rotating
square with other geomtric objects (lines, solids, circles, etc),
interesting and mildly hypnotic patterns were observed. Some were
disturbing while others were somewhat pleasing. Welcome to 101
Basic Graphics!
Many of the techniques displayed here have been modified and
enhanced into forthcoming projects. However, knowing of the lack
of graphic displays and fancy pictures on the Rainbow, this demo
and the upcoming "Gallery Two" attempt to show off some of the
Rainbow's capabilites.
You do not need a color monitor to enjoy the presentation.
But, having one will only further enhance the displays. This
package was created using a monochrome system and it is hoped
that, somehow, someday, a color monitor will exist for us here at
AVSD for the creation of even more graphics.
In considering each display individually:
"Spectral Kalidescope" is the only part of "Gallery One"
making use of 16 different colors in its display. It is still
hypnotic even in monochrome. Now, repeat after me . . .
"Moire Windows" was the basic idea of this package modified
slightly to play with the effects of intersecting lines. At dif-
ferent speeds, the display produces intricate weaving patterns
that constantly change, fade, and then re-appear.
In "Synchronizational Wanderings", there is found a pulsat-
ing solid diamond that randomly changes its color, a rotating
square that produces patterns upon the diamond's surface, and
every now and then a bouncing circle which travels across the
screen following whatever path it desires. If you see dots left
by the intersection of the square and circle, look closely at the
patterns left behind.
"Tandem Journey" is a stereoscopic effect with the same geo-
metric shapes as in the other displays. However, we have a color
changing, tunnel-effect that interacts with the rectangles to
produce amazingand sometimes bizzare patterns.
Finally, "Bounce! The Birth of Zippy Pinball" is the incar-
nation of a graphic pinball game for the Rainbow. This demo shows
a square pinball (!) being richoceted along a myriad of paths.
The pinball encounters the walls and several 'Bounce Boxes'. The
'Bounce Boxes' may at times ignore the pinball until it gets too
close or it may decide to bounce it away before it hits. Some-
times, if the pinball hits just right, it will be swallowed by
the 'Bouncer' and will bounce inside until it can find a way out;
randomly bouncing away. The path the pinball takes is based on
a number of factors. It is possible that completely illogical
richocetes may happen. This is just for fun!
This package of displays is about art. Art means different
things to different people. Some people will like it and others
will not. That is all right. It was fun creating it and I hope
you have fun looking at it. Art will always be full of the known
and unknown; the expected and unexepected. This art, however, is
not expected to do anything harmful to your system or software!
OPERATION -
The presentation is started by invoking the program. A small
window will appear on the screen and, after a short pause, the
demo will start. Five titles will appear and the user can select
between them using the <UP> and <DOWN> arrow keys. Pressing the
<DO> key on the highlighted title will start the particular demo.
To exit a demo while it is running, press ANY key. To exit the
demo and return to the MS-DOS command prompt, press <EXIT>.
Since most of the displays contain numerous pseudo-random
elements, each time you run a particular display it will behave
and look different. There is a fairly wide range of differences
and some will be more pleasing than others. Keep selecting the
same display to view different patterns until you find one you
like.

CREDITS AND ACKNOWLEDGEMENTS -
This package could not have been finished without the help
of Mr. Kenneth Nist. A recent posting of his Turbo Pascal graph-
ic routines contained the two or three critical bug-fixes that
had previously hampered the completion of my own graphics pack-
age. Thanks, Ken!
To all, enjoy!
