A Christmas Tree Screensaver 4.0 Create a Christmas tree for your desktop with this interactive screensaver. In the settings, choose from among eight classic Christmas carols, a background scene, and tree color. These options set the tone as shiny tinsel and baubles adorn your tree. Or, sit back and watch while your computer randomly bedecks your virtual holiday pine for you. The spirit of Noel is capped by stacks of gift-wrapped presents and powdery, falling snow.
