Object relationships on the stage

Alrighty i’m trying to expand my understanding of actionscript and am trying to figure out effects like the navigation at www.kurtnoble.com . I’m trying to make, for practice, four squares like their navigation where one expands and the others shrink to allow room for it. This can be used to do a lot of different things, i know, but i’m just using this to learn it.

I know in the nav on that site it’s all relative to the left, and when you click a box, it scales to a certain size, changes the x coordinates of the other boxes, and has an easing equation with bounce when it moves them. I’m just not very good at math and always have trouble with stuff like this. Has anyone else done something similar who can give me some tips? Thanks.:slight_smile:
