Introduction: Mechanical Iris

About: I like to make inventions, usually out of paper and stuff I have. I have a few projects that i haven't put up on instructables yet...

I made this a while ago and I didnt post it till now. It opens and closes, and it is made of credit cards, paperclips, and foam core. It has six segments.
I am thinking of making an instructable of it.
What do you think?
Also, which image is better? The first or second?

    I prefer the behind view of it...

    Please do make an instructable about this - I've been wanting to make a mechanical iris for ages but haven't got round to it...

    Yes, I was quite adicted to them at the time, I was thinking of buying one but I thought that it would be a fun challenge to make one instead, also they cost alot too

    The better image is the fourth - the one posed like the third, but with the other side of the iris facing the camera.

    How do you open and close it?

    Thanks!
    In the second picture with the metal sticking out, you would twist it, I think clockwise to close and counter clockwise to open it.
