The scroll wheel inside my mouse is a very simple but brilliant mechanism that basically pushes two buttons in succession every time I scroll it fwd one click. The succession of the pressing of these two buttons is opposite if I scroll the wheel in the other direction. Thus it can tell which direction I am turning it and how far or fast I have turned it.
So I de-soldered this scroll wheel from my mouse and replaced it with two fabric buttons which I can now basically gallop on with my fingers to control the scrolling of my mouse and it is a very inconvenient action but I still think it is cool.
