In honor of **Pi Day**, here’s a wonderful example of student creativity: a necklace that encodes the first 80 or so digits of pi in beads!

Starting with the pendant as **3**, the beads and string clockwise, in a circle, according to the following mapping:

Thus, you can read off **3.14159265358**, and so on. A truly thoughtful, creative, and inspired work!

I like the idea of the necklace. Is it possible to contact with the student for authorization to use it on the math literary magazine?

If so, I would be glad to work with him/her.

Very nice. It reminds me of a classic electronic resistor and its color code, though numbers behind there are a bit different.
