    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.
    x: A 2D context for that canvas.

What colour is your easter pig?

u/Agnes

(Sometimes you don't get an easter pig and sometimes the pig is a ghost, but I think that improves the dweet and I don't have the characters to fix either bug)
u/chokezonhorsey

haha.. i love it :))
u/BirdsTweetCodersDweet

Apparently c.width|=q=t<10;f=t?q?(f/Math.random())%9e3:f:1;x.font=512*(q?t/10:1)+'px A';x.fillStyle='#'+!q*~~f;x.fillText("🐖",660+t*q*f%5,740) fixes the ghost pig on mine :P

works after hovering it

u/h3rmanj

probably don't work in older browsers either
u/BirdsTweetCodersDweet

It doesn't work till you hover on it, because v and y have no default values
u/BirdsTweetCodersDweet

c.width=568 t?0:(v=0,y=0) c.onmousemove=e=>{v=e.x,y=e.y} x.beginPath() for(i=88;i--;x.moveTo(300+S(t+i)*200,150+C(t)*C(i)*150),x.lineTo(v,y)) x.stroke() is too long, but fixes the hover issue - maybe you can golf it ;)

What a clever way to do the background. I also like how you used Math.tan to get the trees.
