    That's a very juicy #twister!

    I teach 9-year-olds programming and used a tidied up version of this to show them how to figure out how something works. They loved it! Thanks! I've added a bit of gap between the strands to make it easier to understand, and I think it looks good. Like Math.max(180*S(a-1.2),0).

    wow, i would have never thought that my recreational programming would be used for educational purposes. glad i was able to help those kids out on their journeys!

    Shortened by 10 characters: c.height|= p=m=>(S(Y+t+m*90)+1)*250;for(i=108;i--,Y=(0|i/4)*40;a<b&&x.fillRect(a,Y,b-a,40))x.fillStyle=R(a=p(m=i%4),50,b=p(m+1%4))
  • u/Purpzie
    Oh woops it should be c.height|=p=m=>(S(Y+t+m*90)+1)*250;for(i=108;i--,Y=(0|i/4)*40;a<b&&x.fillRect(a,Y,b-a,40))x.fillStyle=R(a=p(m=i%4),50,b=p(m+1%4))
  • u/Purpzie
    Okay dwitter hates me now, there should be a newline afterc.height|=
  • u/Purpzie
    Honestly there should be an edit button for comments. Forgot to mention I changed the color but it has no effect on code length
