  • Visualising numbers for which sin(x)*sin(x) + cos(x)*cos(x) < 1.
  • u/donbright
    wait wait wait wait wait.... sin^2 + cos^2 = 1. im so confused. is this about the imprecision of floating point arithmetic?
  • u/donbright
    this is absolutely fascinating... set it ==1 or >1 gives different patterns.
  • u/donbright
    also fun... return S(n)/C(n)==T(n)

  • field work

    Awesome! I managed to shorten it down to 129 if you want to add something to it: v=160;s=20;for(i=60*v;i--;l=(i%v))m=(i/v)|0,k=1+S(C(l/15)/C(m/17)+t*4),x.fillStyle=R(n=k*v+m*2,n+m,n+k*v),x.fillRect(l*s,m*s,s,s)
