Press a key a-z and 1-9 to draw a spirograph. Space bar will generate the basic spirograph shape. Left and right arrows will gradually shift the color; up arrow will set color to blue and down arrow will set it to black.
Notes: If you decide that you don't like the spirograph that's currently being drawn and go to press another key, make sure to press the stop button first. Alternatively, press 2+ keys at once to make your own unique pattern (though I can't vouch for whether it will actually create a consistent shape)! Also, to anyone who's remixing this or just looking at the code: LTA stands for 'Line Turning Angle' and CDS stands for 'Current Drawing Step'. Credits: I learned the basics of this (and took the names of the variables) from Paulo Tanaka on YouTube.
