Christi's Tree is simply a Christmas Tree for your Mac. It sits on your desktop or in your dock to give your Mac that extra little bit of holiday cheer that sets you apart from all the PC weenies out there.
Of course it has lots of great features, too. You can add decorations like cranberry garland, red Christmas balls, and even flashing lights. It works in your dock, or as a floating window. And best of all, it's free. Ho, ho, ho, Merry Christmas!
