Pendulum

Not much, but I found it amusing for awhile. It's pretty pointless, and wouldn't be much use in a real movie as it requires the mouse to be kept motionless.

Directions: Just type in a value for friction and speed. They can be negative or a decimal, just anything but 0. Then use the mouse to move the little bar on the bottom left or right to increase the force. The farther away from the center, the greater it is.
