Student..would like some help please? Thank you

Hi basicly i've had an idea for a project im doing at uni, ive found an example of a web banner that i think has been created in flash and would like to know a possible method of doing this sort of effect.

I have touched on flash a bit but do not have a huge knowledge of the subject. My first idea was to draw a grid over my image in illustrator and draw each square on a new layer. Then when i would import this into flash, each square would be on a different layer. From this i would convert each square into a button and have a click action which would rotate the button 90 degrees every time it is clicked. Would this be possible or is there a better method to be using?
Sorry if some of the wording doesn't sound right im new to flash.
Any help with this would be really appreciated thanks. david.

Thats the way I would do it

That sounds like perfect method for this type of project. I think I may have to try it out myself.
