Fly on Desktop

Fly on Desktop is a fun tool for Windows that places flies on your desktop and mimics their behavior. It is possible to launch as many flies as you want.
The setup procedure is brief and uneventful, and does not require special attention. Once initialized, Fly on Desktop launches five flies on the screen and creates an icon in the system tray area, where you can access the control panel and make adjustments.
You can enable the flies to move away from the cursor, make them stay on top of other applications, as well as ask Fly on Desktop to automatically run at startup and set the number of flies to start with. From the right-click menu you can add one or five flies at a time.
The lightweight application has a minimal impact on system performance, running on a very low quantity of CPU and RAM. It works smoothly and doesn't cause the operating system to hang, crash or pop up error dialogs; we have not come across any issues throughout our evaluation.
All in all, Fly on Desktop is a fun utility for playing pranks on your friends and, thanks to its overall simplicity, it can be set up by all types of users.
