Spirograph art by Tushar 

The Spirograph is a geometric drawing toy that produces mathematical curves known as hypotrochoids and epitrochoids. It was developed by British engineer Denys Fisher. Drawing toys based on gears have been around since at least 1908, when The Marvelous Wondergraph was advertised in the Sears catalog.#spirograph#spirograph art #spirograph #spirographart #geometricart #mathart #art #spirography #mandala #lineart #geometric #drawing #geometry #harmonograph #artwork #linedrawing #spiro #abstract #drawingmachine #digitalart #spiroart #spirographs #generativeart #lightpainting #artist #inkdrawing #abstractart #machineart #longexposure #mathematics #ink #spiral#graphicdesign #spirographic #geometricshapes #moire #designart #radialsymmetry #g #spiralart #machine #pintograph #spinart #makingit #artforsale #symmetry #harmonogram #analogdrawing #guillochepattern #pattern #mechanical #wildlines #goldenmean #cycloid #mathartdesign #mechanicaldrawing #wireframepatterns #ratio #gears
