Mechanical Iris

I made this a while ago and it actually works. Some of you might have seen this on instructables, but for the people who hasn't, this is why i posted it here. It can open all the way but it cant close all the way, the segments are too thick. I am making a new design with thinner segments. Instructions It is hard to show it with the few pictures, so here is a link to instructables that would explain it better: http://www.instructables.com/id/Paper-Mechanical-Iris/
