CocoaBeam is a stage light visualization tool for Lighting Designers. CocoaBeam is available as a fully functional version with source code (GPL 2.0) with a library of common lighting fixtures. The full version allows access to the Instrument Inspector and the ability to add instruments and save instrument collections. I'm not planning any future releases of CocoaBeam, but the source code is available in the download.
Version 1.0beta1: Initial beta release. Source released under GPL.
Mac OS X 10.4 or later
