Horizontal flash display - without scroll bars

A website with a horizontal scrollbar was just submitted for reference, but this one doesn't have it!

This should be a pajama product showcase website. The main site design is very nice. After entering this subpage, there's a model displaying the products with horizontal scrolling. Using appropriate mouse events can create great effects, such as fade-in and fade-out.

The only issue is that the loading time is a bit slow after opening an internal link～～It seems like these kinds of effects can only be achieved with Flash, but I wonder if JS can do it?
