Polar Coordinate Etch-a-Sketch
19 Nov 2015Progress: Demo
Escape the Cartesian system! One knob controls angle, the other controls radius.
Above is a browser-based simulation of a polar coordinate etch-a-sketch. Use the arrow keys to control the knobs (up/down for radius, left/right for angle), and shake it using your mouse to erase.
Update: added touch screen and accelerometer support. Twizzle the knobs and shake to erase.
