Camera Shutter C4D Animation

I already search the web, but couldn't find a decent solution.

(1) There is an old thread:

However the link of the file is dead.

(2) I also found a C4D file, but the site does not allow me register to their database. It says my country is not supported. :/

Basically, I want to animate the opening of the blades, like in this image.

I don't have a firm ground on C4D (just the basics) so I don't know where to start with the animation, let alone the proper tools to make it. I badly need help.

The setup is easy, but the animation is a bit problematic. I was hoping its some sort of sine-wave but I'm not sure, neither I'm good at trigonometry, nor have the time. Play around with the two formulas in the xpresso tag, maybe you can get it right.

Or you try it using the bool and array object.

Sorry it took me awhile to respond. The internet was out for about a week.
First off, thank you for the project file, :]

So, here is just my concerns regarding the files:

(1) I can't use the "formula" project, since its using xPresso. I just can't understand it ATM. So what follows is related to the "array" project, (though I believe it would be more accurate using xPresso)

(2) Thankfully, I understand the array project, and managed to re-do what you did and just made it into 9 equal disc. My another problem is that as the "aperture" widens, the blades becomes more and more apart from each other.

Is there anyway, I can maintain their distance, like in the first post illustration?

Here is the image.

Sorry for the trouble again, and I hope you'd help me again.

My suggestion is to do a Google image search to find out how a camera iris is actually constructed. A very quick result relying on that thought:

Okay mate. Thanks for the reply :]
