This is a browser glitch, right? It only looks cool because the browser starts using too few segments to draw the spiral. Would be boring in a fixed browser.
u/Haabilo

@sparr Not really a glitch. The code uses lineTo as means to straw the lines. It also sets the maximum amount 5
u/Haabilo

...of the segments. Damn, I didn't think mistapping backspace on mobile would send the comment as-is...
