Non-Imaginary Necklace

0=1+e^(-pi*i)
Of the necklaces I’ve made for 365 Necklaces so far, I think this one has been the most fun. It was a request from my friend Moritz to do what I could with the mathematical imaginary unit, i. He made it easy by giving me his favorite equation for i (see caption above) and I turned it into a very not imaginary necklace.
I used a variety of encodings and color codings. The mathematical operators (= + ^ – * )are done in 7-bit ASCII binary in silver beads. The numbers and letters are also ASCII binary, but red. The two constants, e & pi are picked out in numeric form with silver beads for decimal points (and pi is a circle, of course). I hammered some silver parentheses for a change of pace.
There are still some openings for a free necklace of your own, so if you want one, please comment on the offering post before it is too late.
