Deskflag allows you to quickly hide and show your desktop icons.
Do you have cluttered Desktop and just don't want to see It more? If you just want to give a presentation and don't want your audience to see your desktop icons, Deskflag is the right software for you. Deskflag sits in the menu bar and in the Dock. Launch It and click the menu bar icon. A dark transparent window is presented to you. You can Show/Hide all icons in one shot, or you can select individual icons in the listbox. Double-click an item and you're done.
Note: Now requires a 64-bit Intel processor.
