Tiny screen saver

tss.mp4

About

The goal of this project was to write a fully functional Windows screen saver (including preview and settings) in around 1024 bytes. The current size is 1292 bytes.
The screen saver implements a 2D Cyclic cellular automaton using the first 16 colors of the default Windows color palette.

WARNING: the screen saver executable can trigger antiviruses due to compression.

Building

Open the project in Visual Studio.

Alternatively:

cd tiny-screen-saver
cmake -Bbuild -DCMAKE_BUILD_TYPE=Release -GNinja
cmake --build build

The USE_CRINKLER CMake option allows to set crinkler as the linker. The default is ON.

Installing

To install the screen saver the produced tss.scr needs to be copied to the Windows System32 folder.
The build script will do this automatically if it has admin rights.
After that select the Change screen saver option in the Windows Control Panel and select tss from the list.
