[jQuery] How can animate Background at specific intervals with specified range.


Hi all,
how to change background position at random or specified range with x,
y axis when mouse rolls over.
Ex: Background Image height is 200px. When mouse rolls over it will
change specified x, y position, like (0, 20), (0,40), (0,60)...
thank you
