Technical notes, math flavor: Yesterday’s POW bracelet was based on this function:
If we put the “2” weight on the cosine instead of the sine then we get the function for today’s bracelet:
If you look at the POW and the POP bracelets together you can kind of see how each one is sort of “inside-out” from the other. Of course the function we wrapped around the circle to make the POP bracelet needed a modified shift, amplitude, and frequency:
Finally, here it is wrapped around the circle as a parametric function:
