    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.

Optical illusion I saw somewhere. All the rows and columns are perfectly straight.

Color change over time to help keep track of the wee sot.

u/asciislinger

Really cool. I'd love to add a way to keep him on the canvas.

First draft of a #beesandbombs wave https://twitter.com/beesandbombs/status/1113…

u/pavel

You want something like for(c.width|=y=20;x.fillStyle=['blue','gold','red'][--y%3];)for(i=500;i--;)x.fillRect(z=680+i+y+C(y/3-2*t)*200,200+y*40+S(z/9-3*t)*18,4,4)
u/joeytwiddle

Tweaked colours and numbers a little: for(c.width|=y=27;x.fillStyle=['#47a','#ec2','#d66'][--y%3];)for(i=450;i--;)x.fillRect(z=680+i+y+C(y/4-4*t)*200,100+y*33+S(z/12-6*t)*18,6,7)

Already done: d/11284
u/robbyg

Yeah, I saw that after scrolling for a while in #default. But it's a different take at least.
u/katkip

^ similar one but this is more smooth
u/lionleaf

I enjoy the default remixes. This one is soothing :)

I hadn't played with an #attractor lately. They really play to my strength of "change random stuff until something neat happens".

u/taupelink

That's my method too!
