Curvarium — A Museum of Living Curves
An interactive gallery where mathematics becomes art. Ten living exhibits — roses, Lissajous knots, the golden-angle sunflower, Fourier's square, Ulam's prime spiral and more — each drawn live, each with sliders to bend the math and a Morph tour that animates the whole family of curves. For students, teachers, and anyone who suspects equations might be beautiful.
