The central source for quartz composer creations.
Compositions shared through the site. The original files are no longer hosted; archived copies of many of the download pages can be found through the Wayback Machine by searching the file name with "quartz composer".
Talker, a screensaver. EarthWeather, which pulled live weather imagery onto the desktop. AsteroidsQC, an Asteroids clone built entirely as a composition. A Glowing Neon Analogue Clock. Alongside these were many screensavers and example .qtz files.
Compositions are .qtz files and open in Quartz Composer on a compatible version of Mac OS X. Many also run directly as screensavers when placed in the Screen Savers folder.
