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