Google's homepage is one of the most coveted pieces of design real estate on the internet. Every March 14th, it becomes a celebration of Pi Day with a custom-made Doodle. The 2026 edition was part of Google's Learning Series, meaning it needed to do more than delight: it had to inform.

The Doodle visualizes Archimedes' polygon trap — a method of approximating pi by inscribing and circumscribing regular polygons around a circle and increasing the number of sides until the perimeters converge. As design director, I helped develop a cut paper aesthetic to make the concept tangible: a shape whittled down edge by edge, iteration by iteration, until it becomes a circle. The approach balanced tactile approachability with conceptual clarity, leaning on geometric forms and a graphic design sensibility to make a 2,000-year-old mathematical method feel immediate and pleasing.

This Doodle ran globally on one of the world's most visited websites, potentially seen by billions of users.
