    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.

I spent about a full day trying to figure out a bitmappy way to make a houndstooth pattern, but I couldn't get it under 140 characters! Decided to go the boolean logic route instead.

previous attempt (158 chars): p=[8,4,2,1,9,13,15,16,273,2321,3345,3857,4113,2065,1041,529].map(_=>_*15) for(i=0;i<213;i++)for(j=0;j<120;j++)(p[j%16]>>(i%16))%2==0?x.fillRect(i*9,j*9,9,9):0

I just posted remix #5365. I've been experimenting with converting UTF characters to binary data. See also my other dweets :)

Nicee
u/Ath0r

Thanks! It's the first time I've tried, so probably I missed a lot of tricks to reduce characters... Any feedback or tips are welcome! :D
u/13thptr

b is unused so you can remove it :)

nice dweet btw

Thanks a lot for the suggestions, @13thptr! Indeed, I forgot to remove the unused b and the characters you remove by avoiding the definition of p is also very nice :)

It's a spinning simplex!! :D great 1st dweet
