As its name says, Fly on Desktop does nothing else but puts flies on your desktop. The thing is that it simulates the appearance and the behavior of the flies in a truly impressive, realistic manner, so you won’t be able to tell the difference between a real fly that landed on your monitor and the ones generated by this program.
Fly on Desktop is a really lightweight and neat tool that won’t consume any system resources. It also comes with handy options. For example, it lets you change the number of flies on the screen. You can add 5 flies at once with a single click. You can also define the number of flies that appear when you start the program. Setting the program to run automatically at system startup is also possible.
As you can see, this free application represents a great manner to prank some friends or coworkers into thinking that their desktops got infested with flies. The program doesn't have any specific purpose, but it is really funny and it may help you to spend your free time with some entertainment.
