Introduction: Mechanical Iris
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?
