Spirograph
Interactive spirograph drawing with nested spinning circles on HTML5 canvas.
About Spirograph
Pick a pen color, set the radii of two nested circles, and watch as the inner wheel rolls around the outer one, tracing a continuous looping curve on the canvas. Adjust the ratio and the pattern shifts from a simple rosette to a dense star with dozens of overlapping petals. Each run is deterministic — same settings, same shape — so it rewards deliberate tweaking more than random clicking.
It belongs squarely in the creative apps category, sitting closer to mathematical art than freehand drawing. There's no undo stack or layering system; the appeal is in watching geometry emerge in real time. If you want to do something with the colors you land on, Color Palette Builder is worth a look for capturing and saving them.
Works best on a desktop or laptop, where a larger screen lets the full curve render without the edges clipping — and you can fine-tune numeric inputs with the keyboard rather than fighting a small touch target.

How to use
Create complex geometric patterns using virtual gears that rotate and draw lines as they move. • Click and drag to adjust gear settings in the sidebar • Add multiple gears by clicking the "+" button - each gear can rotate inside or around the previous one • Adjust each gear's size, speed, and drawing point position using the controls • Click "Draw" to start creating your pattern - the virtual pen traces the path as gears rotate • Use "Clear" to erase the canvas and start over • Try "Random" for automatic gear configurations • Experiment with different gear combinations - more gears create more intricate designs • Each gear rotates relative to the previous one, building complexity • The drawing point on the final gear determines what pattern gets traced • Save your creations by right-clicking the canvas Goal: Experiment with gear combinations to create beautiful mathematical art patterns, just like the classic Spirograph toy but with unlimited possibilities.
