    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.

fillText Y=i==52?Y-T:Y+T, but can't animate with this method. Don't think it's going to be possible in 140 ether.

#chess board

u/FireFly

I've stared at this for too long... don't think I can get it below 146 decompressed (with Z inlined). Would be rad if we could squeeze those last characters out though and get it down to 140 without compression :)
u/tomxor

I have an imperfect 142
u/Agnes

This is 145 but I don't remember if the new indexing is actually shorter or not than yours: for(i=w=128;i--;x.fillStyle=R(i%2?x.fillRect(X=i%16*64,Y=i*8&-w,m=X+Y&w,m)|w:x.fillText('♜♞♝♚♛♝♞♜♟ '[Y++%7?++Y%5?9:8:i/2%8],X,Y+w)))x.font="4cm'"

u/TGY

now we need to combine 2 dweets into single XD
u/DataMeta

fit them together with compression, but would be more interesting to jam it into 140 :)
u/FireFly

I can do a full chess board in 151c currently, but it *would* be really satisfying to fit it into the 140c without compression tricks indeed

Text positioning tweaked on a Chrome on macOS, so may look screwed up on other browsers.
u/magna

Also, holy shit. Look at those artifacts around the skunk. Who at Apple cleaned that image?
u/magna

*Apple -> Chrome/Google? I don't know who is responsible for the emojis :)
u/mxfh

Lol. Apple Skunkworks I suppose. dwitter is a whole argument while real other browsers should be enforced to be allowed on iOS.
u/rep_movsd

Chromium doest show the skunk :(
u/tomxor

Safari/webkit is the new IE in terms of browser stagnation and bugs, i come to dwitter to not care about it :)

Some nice math for the 270 initial radius: The half-height is 540, this must equal r+r/2+r/4+r/8+...=r(1+1/2+1/4+1/8+...). Think about the bit in the brackets in terms of pizzas. You have a whole pizza, plus half a pizza, plus a quarter (half the remaining half), plus an eighth (half the remaining), etc. You have two pizzas! So 540=r*2.

Remix of d/11587. I remixed my other remix but that one was boring so I deleted it.
u/ciaccodavide

nice!
u/cantelope

i think about everything in terms of pizzas
