Just launch and find yourself getting into the spirit of the season. The lights hang from the menu bar and will stay just above the desktop and under everything else. Adds a festive mood to any computer.

Very small (just over 400k), very process friendly (won't slow you down) and very festive. Now supports 10.4 again.

To add new light styles, simply name the new lights <name>1On.png and <name>1Off.png. Then put these image files into ~/Library/Application Support/XMas Lights and they will be found when you open the preferences panel. You can string together multiple lights by naming them sequentially as <name><n>On and <name><n>Off. As an example, I have two lights to string together, and I name them MyCoolLights1On.jpeg, MyCoolLights2On.jpeg, MyCoolLights1Off.jpeg, MyCoolLights2Off.jpeg.

If this makes you smile at all, drop me a line at gooddoug@gmail.com and let me know! And thanks to our users for providing more light styles. Thanks also to Jason Hayes (jhayes@willamette.edu) for his enthusiastic help with ideas, code and artwork.
