If you like to stuff blinking lights, elfs or Christmas trees into and around your house as soon as the Christmas season nears you might also like the desktop Christmas tree.
The Christmas tree require no installation and can be executed after unpacking them on the computer. They are always on top by default and can be moved freely around on the computer desktop.
The transparency of the Christmas tree can be configured by right-clicking it. The same menu provides access to the always on top parameter.
