This application was created mainly for fun, but it might prove useful if your mouse clicks don't work properly. Basically, CheeseMouse simulates mouse clicks on your computer. You move your mouse as you normally would, but you press the CTRL key on your keyboard to simulate a mouse click. If you hold it down, 64 clicks per second of either the left or right mouse button (left and right clicks correspond to the left and right ctrl keys on your keyboard).
And since 64 clicks per second isn't usually that fun, there is an optional n00k mode that allows you to toggle (again, with the control keys) ~2500 clicks per second. Just for fun, you could try enabling n00k mode and moving your cursor across your desktop. This version is the first release on CNET Download.com.
