Jquery Marquee - repost

I need a marquee for an image gallery, that speed and direction will change according to the location of the mouse over the marquee. There will be a center where the location speed is 0, and when the cursor goes up the direction is set to up and the speed increases as the mouse goes higher, and as the cursor goes down, the speed decreases. When the cursor reaches the middle point, the direction is set to down, and as the mouse goes down, the speed goes up. For instance: | -> direction up, faster | -> direction up | -> middle point | -> direction down | -> direction down, faster I need to see a demo if possible, maybe something similar. Time is of the essence here. Budget $30.
