Arithmos, an atlas of mathematical wonders
An interactive mathematical atlas that explores 40 shapes through animations, visual lessons, worked examples, documentation, and C code.
Field notes
The atlas groups its material into filters such as Quadratic worlds, Hidden sequences, Primes & spirals, and Rational geometry, giving the collection a browsable structure rather than presenting isolated demonstrations. Individual entries pair an exploration with separate Graphic, Docs, and C code links; examples include the Sacks spiral, where prime n is placed at radius √n and angle 2π√n, and the Integral Apollonian gasket, built from integer bends and tangent circles.
