PresenterMate is a great tool to make your Mac desktop look clear and unobstructed during presentations, demos and screen-casts, and even to just clear the desktop so you could clear your mind. When you open the application, PresenterMate puts an icon in the right side of your menu bar, and all the icons of folders, files, pages, pictures and anything else that might have cluttered your desktop, it all disappears from view. Close the application by clicking a button in the menu bar and all the icons come back.
Time Lapse Assembler allows you to create movies from a sequence of images.
