camera iris shutter effect?

Does anyone know of any example of a camera iris shutter closing? You know like at the start of James Bond films. I only found one example in the Movies section and it doesnt have the 'petals' touching all the time like actually happens in a camera lens.

Im sure its not hard to simulate but i just cant seem to get the shape of the 'petals' right or the pivot points in the correct place.

Even if some one has a mpg or animated gif of a camera iris closing i could work it out from that.

cheers

do a search through this forum..

I remember someone trying to build one a while back.

There was a uploaded file if I remember rightly
