Cycloids Shirt — Mathematical Geometry Graphic Tee

The Cycloids Shirt turns mathematical curves into clean, wearable graphic art.

Three circles sit in a horizontal row across the chest, each filled with a different construction of fine geometric lines. The changing points of convergence create three distinct patterns, showing how repetition, motion and mathematics can produce unexpectedly intricate forms.

Minimal from a distance and detailed up close, this original BkTek Apparel design is made for math enthusiasts, geometry lovers, STEM students, engineers, teachers and anyone drawn to the visual side of mathematics.
