Random rollover navigation - Help

Hi all!

I am trying to figure out the navigation at http://www.chipotle.com

There is this random image that appears everytime your mouse rollover. If you guys noticed, when it rollover to rollout, the animation seems to control by the x y position of the mouse. It seems logical to be done in animation but not by actionscripting. Would love to get some tips on using actionscripting(randomness) or whatever to do this. Thanks!

first of all : the navigation is not random!!
i noticed that there are first the chips, then peas and then the tomatoes
but they are just switched when you rollout a specific invisible circular area :slight_smile:

oh yeah. thanks!
