SpinDoodly turns simple finger gestures into mesmerizing rotating art. Drag, swirl, and let the canvas spin — every stroke sweeps into hypnotic patterns you can't stop watching. Two modes, endless possibilities: SPIN DOODLE Continuous strokes that bend and curl as the canvas rotates beneath your finger. Add spikes for sharp radial bursts. Add drips for melting lines that fall outward. Mirror with symmetry to instantly turn one stroke into 2, 4, 8, even 16 perfectly aligned reflections. SPRAY DOODLE Spray paint with dots, oriented lines, or stamp shapes (stars, hearts, hexagons, flowers, and more). Adjust spread with the Fibonacci dial to layer perfectly distributed patterns — phyllotaxis-style spirals straight from nature.
