Spirograph Maker vs FlipPhonic

Create mesmerizing geometric art with a single tap. Released in 2017 with over 110,000 downloads — a math-meets-art tool refined over 9 years. Spirograph Maker turns the timeless mechanical drawing toy into a digital playground for your iPhone and iPad. Choose your gears, pick your colors, and watch hypnotic patterns bloom across the screen — no drawing skill required. WHERE MATH MEETS ART The patterns Spirograph creates aren't accidents — they're governed by GCD/LCM and parametric equations. Watch how the lobe count is determined by n/gcd(n,m), see hypotrochoids and epitrochoids come alive on your screen. A visual companion for middle-school number theory and high-school parametric curves. Whether you're a curious learner, a math enthusiast, or just love beautiful patterns, this is where math becomes mesmerizing. In 2022, this app was acknowledged in an academic paper on algebraic combinatorics — the smoothness criteria for Positroid varieties (Billey & Weaver, arXiv:2207.06508). From a child's toy to cutting-edge mathematical research — that's how deep these patterns go. FOUR GEAR SHAPES Not just circles. Draw with ellipse, rounded triangle (a curve of constant width), and teardrop gears too. Change the gear's shape and the symmetry of the pattern changes with it: circles stay regular, ellipses stretch, triangles beat in threes, teardrops curve organically. A strength slider tunes each shape continuously — from nearly circular to a flat ellipse, or a sharply pointed triangle or teardrop.
