AMAZING! Btw, you can save 3 bytes without changing the visuals or camera path by using fillRect(i,j++,2,~h) ;)
u/jylikangas

Thanks all! p01 - I didn't know fillRect takes negative height. That's gonna save bytes in my other demos too - big thanks for the tip!

I used a golf trick to plot for only 2 seconds: x.fillRect(...,...,...,t<2). If time >2 then the pixel height will be zero.
