It includes support for MIDI, QuickTime playback through Core Video, real-time Core Image filters, audio & video capture, external data sources like RSS feeds or Spotlight, simple JavaScripts and much more… the result of which can be integrated into an application, saved as a standalone viewer, or exported as a Mac OS X screen saver module. All of this functionality is accessible through an simple graphical interface and without writing a single line of code.
