Golden Ratio Calipers

I would not have thought this possible, or at least I would not have thought to attempt this. But Amida Na did and I'm so happy for it. If you do not know, the golden ratio is both a mathematical and aesthetic ratio of about 1.618 to 1. Look at your fingers, each digit is about 1.618 of the next. Artists have been using calipers like this for ages, and now LEGO builders can too.
