Quartz Composer

Quartz Composer is a development tool provided with Mac OS X Tiger (as part of the Development Tools package) for processing and rendering graphical data.

It was formerly known as PixelShox Studio, and there's a Yahoo! Group for it.

It is also the one thing that beats super glue for keeping eye candy nuts stuck to a Mac for hours on end.



  • qtzrendang, an app for rendering compositions to movie files.
  • qtzplayer, a command-line player to run compositions full screen.
  • qtzplugin, a way to send inputs to a composition over the network.
  • quartzcomposer-exporter, a way to record QT movies without dropped frames.
  • rdqutils, a set of useful patches to import all sorts of data.


I keep forgetting that plugins in Snow Leopard have to go into the ~/Library/Graphics/Quartz Composer Plug-Ins.
