SpinDoodly vs Kaleidron

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.

A kaleidoscope you build by hand. Drop a shape into one wedge of the mirrored barrel and it repeats into a rosette — six times, or twelve, or three. Move it and the whole pattern moves with it. That is the whole idea, and it turns out to be surprisingly hard to put down. BUILD IT YOURSELF • Thirteen shapes, from flat polygons to tumbling 3D solids • Glossy, matte and metallic materials • Twenty-two colours, plus a wireframe option that draws edges only • One to twelve mirrors — change it and the composition stays, the symmetry doesn't • Nine barrel backgrounds, dark through to light • Tap to place, drag to move, hold to delete. Undo and redo throughout. TODAY'S KALEIDRON A new composition every day, generated from the date — the same one for everyone, everywhere. Open it, keep it, or paint over it. Tomorrow brings another. A PHOTOGRAPH, FOLDED Point the barrel at a picture and it becomes the source material. Frame it against a live preview: the same photo gives a completely different rosette depending which part of it reaches the wedge. Your shapes sit on top of it. ZEN Full screen, no controls, nothing but the pattern turning. Five looping ambiences, or silence. KEEP AND SHARE Save compositions to a gallery and come back to them. Export a still image, an animated GIF that loops without a seam, or set the piece as your wallpaper. YOURS, AND PRIVATE No account. No sign-in.
