“Pi One” is a generative homage to Bitcoin Pizza Day, spinning the story of that first ₿ transaction into an interactive pizza‑slice canvas. Each mint renders a unique circle of 6 or 8 slices against one of five background hues; click any slice to nudge it, make it vanish, or bring it back. A nod to both the first BTC‑pizza swap and the unity of community sharing around a slice of π-pie.
