The 5.2 version of Holiday Lights for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application lies within Theming Tools, more precisely Multiple Desktops. We recommend checking the downloaded files with any free antivirus.
From the developer:
Holiday Lights places rows of festive light bulbs around the edges of your screen, plays holiday music, and includes a screen saver.
