OVERVIEW
The Psychedelic Screen Saver Collection is, as the name so cleverly
suggests, a collection of screen savers that generate an endless variety
of mesmerizing patterns. As the patterns materialize on your screen, the
colors will shift, undulate, and generally speaking, look cool. Whether
you're into abstract art, mathematics, or just have a history of mental
illness, you'll love these screen savers.
Included in the collection are both 16 and 32 bit savers for Microsoft
Windows 3.1, Windows 95, and Windows NT. Also included are versions for
Berkeley Systems' After Dark v3.2
BACKGROUND
The algorithms I used in these screen savers were originally conceived as
part of an art project I worked on in my senior year at the Evergreen State
College. I implemented the algorithms in about 70,000 lines of Borlands'
Turbo Pascal for MS-DOS and included a "User Interface From Hell" that
provided access to the hundreds of parameters used to customize the image
generation process. After I graduated, I attempted to make a living as an
artist by selling the images I produced to various galleries around the
country. I quickly discovered that being an artist requires not only a
healthy dose of creativity, but also a boatload of marketing savvy (which I
was lacking). Since I was having a hard time making ends meet, I decided I'd
have to find another way to make a living (besides, another month of macaroni
and cheese would probably have killed me). After kicking around the idea of
putting together a company to do the video/effects for raves, I decided that
I'd be better off getting a programming position with a company that wouldn't
require me to wear a suit. In order to prove I'd done some programming, I
ported some of my Pascal code for MS-DOS into C for MS Windows and sent it
out with my resume. The result was the beginning of the collection of the
screen savers included here.
SYSTEM REQUIREMENTS
Suggested:
* 386 (preferably with math coprocessor) or better <g>
* Microsoft Windows NT, Windows 95, or Windows 3.1
* 256 color display card - While the screen savers should still work in
high/true color modes, you won't get palette animation.
In order to get some of the effects that they use, the screen savers use
a palettized video mode. This means that colors are referenced by index
rather than by RGB value. By using a palettized video mode, the screen
savers can change the RGB value that corresponds to a particular palette
index and the result is that all of the colors on the screen that use
that index are immediately updated. Neither high or true color modes use
a palette, so it is not possible to achieve the effects without manually
updating the entire display. Since updating the entire display is far
too slow, I didn't code the screen savers to do it.
On the bright side, Windows 95 supports dynamic video mode switching
which means that the display mode can be changed without rebooting the
system. Unfortunately, most of the drivers that are available now don't
handle changes to different pixel depths very well. Once the video
driver writers get their act together, I'll setup the screen savers to
change to a palette based video mode when they start up and then change
back when they are done. However, until then, we're stuck with the
limitation :-(
INSTALLATION
WINDOWS NT:
To install the 32 bit versions of these screen savers on Microsoft Windows
NT, extract the files contained in WIN32.ZIP and then copy them into your
SYSTEM32 directory. This directory should be a subdirectory located in
the directory that you installed Windows NT into.
For example C:\WINNT35\SYSTEM32
WINDOWS 95:
To install the 32 bit versions of these screen savers on Microsoft Windows
95, extract the files contained in WIN32.ZIP and then copy them into your
SYSTEM directory. This directory should be a subdirectory located in the
directory that you installed Windows 95 into.
For example C:\WIN95\SYSTEM
To install the 16 bit versions of these screen savers on Microsoft Windows
95, extract the files contained in WIN16.ZIP and then copy them into the
directory that you installed Windows 95 into.
For example: C:\WIN95
In order to get Windows 95 to use the new screen savers, you will need to
select one of them in from the "Screen Saver" page in the "Display
Properties" dialog. To get to this dialog, you can right click on the
desktop and select "Properties" from the pop-up menu. From the "Screen
Saver" page of the "Display Properties" dialog, use the drop down list box
to select one of the new screen savers. The 16 bit savers from the
collection will appear with the prefix of "MI" (MI Cyclics, MI Patterns,
etc...) while the 32 bit versions will appear with a "_32" suffix (Cyc_32,
Pat_32, etc...). Select one of the new screen savers and then adjust the
settings using the "Settings" button or preview the saver using the
"Preview" button.
WINDOWS/WFW 3.1n:
To install the 16 bit versions of these screen savers on Microsoft Windows
3.1x, extract the files contained in WIN16.ZIP and then copy them into the
directory that you installed Windows 3.1x into.
For example: C:\WINDOWS
AFTER DARK 3.0n:
To install the After Dark versions of these screen savers, extract the
files contained in AD30.ZIP and then copy them into the directory that you
installed After Dark 3.0 into.
For example C:\AD
In order to get After Dark to recognize the new modules, you will need to
go into the "Advanced Options" in the "Setup" section of the After Dark
control panel and press the "Update Module List" button. For earlier
versions of After Dark, you will need to close down After Dark and then
launch it while holding down the control key on your keyboard.
