I have the same thing on my computer, its called Festive Lights. I don't know what kind of computer Du have, but for this particular one Du need a mac and it will display on your dashboard. If Du want to get it off the dashboard Du can Von opening the terminal and entering
defaults write com.apple.dashboard devmode YES
(then press enter)
killall Dock
(then press enter) then Du will be able to go onto your dashboard and grab whichever widget Du want and hit the dashboard button again to bring it to the desktop.
Here is the link to download the festive lights:
