Loadsaver (OS X Screensaver)
A downloadable screen saver
I was playing around with Quartz Composer and made this .qtz (OS X) screensaver.
Sharing because I think it's funny and would make a great practical joke (for mac people).
Install instructions are provided in the .zip.
Place "loadsaver.qtz" file into ~/Library/Screen Savers.
You can get there by pressing ⌘ + Shift + G while in Finder.
Open System Preferences > Desktop & Screensavers and select loadsaver.
Enjoy the infinite loading!
