This is the first step in my Etch-a-Sketch clone. I need to come up with a creative input method. Something gestural, like everything else these days. Anyway, it’s just a rudimentary Processing sketch to imitate the X-Y control of an Etch-a-Sketch, but with the ‘,’ and ‘.’ keys for left and right, and the ‘a’ and ‘z’ keys for up and down. (Do those sides correspond to a real Etch-a-Sketch?) And the ‘c’ key clears the drawing.
Here’s the link to My Itch-o-Skatch sketch.
