Change your desktop
I’ll happily admit to being a bit of a desktop wallpaper collector, and I do also dabble in creating skins for applications. Anyhoo, if you need to get some unusual desktops for your PC I highly recommend you visit mandolux.
As the site itself says: “Mandolux is the number one website for high-end aerospace, paper money, and art desktops on the Internet.” (arguable but possibly true).
