Five shapes, with two sides, on a nail, create 3520 artworks. There were actually 3840 possible combinations, but 320 were redundant. These 320 occurred whenever the smallest shape (the ring) was obscured by the two largest (the triangle & swipe). So whether the ring was color or white side up, made no difference.
The shapes were manufactured to my specs, by Y-3, to accompany the MOMOxY-3 Hayworth Mid II
