AS - adv (I think) mask movement

Hi,

check out this site: http://www.dhondt-deuren-trappen.be/

does anyone have any ideas about how to achieve this effect.

I was thinking just a basic mouse location statement
Pseudocode!
if(mouse location over mc)
enlarge this
shrink other mc relative to this mc
else
move back to start position

I think this should work as mc will only react when gets a mouseover, otherwise they will attempt to return to normal.

What kind of transition function would be best to use for this? I assume the standard mx.transition stuff would cause problems?

thanks in advance
