As a child this was my first PC game. Even if it wasn't a PC game.
The Unofficial Flying Toasters Replica Screensaver
A downloadable tool for Windows
It may have been defunct for more than a decade, but now, an unofficial recreation of the infamous Flying Toasters screensaver exists again for modern hardware!
If you're downloading the installer, it's self explanatory. Just run the executable.
If you download the raw files, right click the flyingtoasters2017.scr and select "Install."
The source code is a .MFA file for use with Clickteam Fusion 2.5 Developer. It requires you to have the File Object, YASO Object, Cursor Object, Open URLs Object, and Window Control object installed.
