Fc.tape is a jQuery UI widget used to create sprite animations.
It works by cycling through a sprite that contains a number of images (similarly to a movie reel) and provides methods to control the playback.
It is possible to step between each frame and play between specific frames. A smooth option adds an extra level of smoothness to the playback.
There is also a rotate mode where the frames can be rotated by clicking in the frame and controlling the animation.
