I haven't played with this in depth, but maybe you can glean something from this page.

Look for the text: 'Example 2 : panoramic views'

Thanks dgreenhouse. Was looking at it but its not quite the desired result. I should let you know that I am a newbie to this stuff. I just really want it to stop when onmouseover and to continue the effect onmouseout.

Does this plugin have an in-built parameter or do I have to define some event code? Thanks for any help.
