About DarkSide…

DarkSide is an application and plugin (faders) based screen saver, giving you a high degree of System compatibility, along with using very few of your System's resources.

DarkSide is freeware, which means that you can use it yourself or give copies away to anyone you wish, but that the rights are retained by the author, Tom Dowdy.

Allows movies, custom modules and some third parties... including many After Dark 2.x modules.
A note about the downloads available from above:

The above files can also be downloaded from Tom Dowdy's site, which is currently still active.

The Manual download holds a PDF´ed version of the Readme file.

Architecture: 68k PPC

Any Mac running Mac OS 7.0 to Mac OS 9.2.2
Version 2.5 runs in SSW 6 and 7 (Requires MultiFinder active in SSW 6.x).
Version 4.2 contains an additional INIT (Control Panel) named "Snausages" included in the DL. I don't know why Tom Dowdy included this, as it is unrelated to DarkSide. Its ReadMe doc has the comment "Inits are evil, and silly: this one especially so. Don't say I didn't warn you!" — YMMV.

Added a PDF of the ReadMe for version 2.5 (1991), converted from MacWrite.

@mrpippy. Thank you for your post. I had not learned of Tom Dowdy's death until now.

I have enjoyed using his DarkSide for so many years now I'm unsure of when I first installed it onto a Mac, tho' it was likely in the early to mid 1990's.

Curious his web site is still alive, 9 years since his passing.

Tom Dowdy passed away in 2008, after working at Apple for 20+ years on many teams: DTS PIGS (Printing Imaging & Graphics Support), QuickDraw GX Printing, QuickTime, and iTunes. Apparently he even wrote SimpleText! Another remembrance: Remembering Tom Dowdy
RIP. His software lives on.

If anyone has the source to all or some / one of the modules please let me know

The DL to version 4.2 above and on Tom Dowdy's site, contains the source code to 2 of the modules.

Included with the release of DarkSide is source to two simple faders - Invert and Morpion - that shows off all of the basics you'll need in order to write a fader.
You can find example MPW and Think C (version 6.0) source on the release disk with DarkSide. This is the actual source to Invert and Morpion.

Further information regarding those included modules can be viewed on the DarkSide Documentation pages.

It states in the DarkSide documentation that the source code to all the modules is available upon request (and payment of a small fee) from Tom Dowdy. Despite having sent multiple emails to the address given on his official website I have never received a reply from Tom Dowdy, which I think is a little rude personally (I made it clear I would happily pay the fee, it's not like I was asking for a handout). He may no longer value it, but it's a part of the history of the Mac and screen savers in general.

If anyone has the source to all or some / one of the modules please let me know or share it as an additional download on this page. I would really love to study some of it and possibly use it as a basis for creating new DarkSide modules to enjoy myself and share with the community here.

I couldn't agree more, Forth is the greatest DarkSide module by far, and possibly my favorite fireworks screen saver of all (which is saying a lot; I have a massive collection of "Fireworks" screen savers for multiple platforms including Win 3.1 / 95). I like it so much I tried to locate the original author of that module (it isn't Tom Dowdy like most other modules), but was unable to track him down just by his name which is all that's given in the modules "About" section.

If anyone knows him please let me know.

Man, I could stare at the Fourth screensaver for hours. It is on every one of my PPC Macs right now.
