The theme chosen for the 2025 International Day of Mathematics— or Pi Day, as dates are written in some countries: third month, fourteenth day— is Mathematics, Art, and Creativity. This provides us the perfect opportunity both to launch a participatory maths art activity, and to consider mathematical art more generally. With a focus on properties of Pi, come for an evening stroll past mathematical visual and textile art that I hope will inspire your own creativity. Yes, there will be circles, but so much more.
