    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.

Limited Range Delta Compression - Fit 200 chars! with extreme limitations :D

Show more comments…
u/tomxor

Each char is encoded as 5 bits (fitting 4 into each 20bit surrogate pair), representing the numeric difference between the previous and current ASCII codepoint. Since 5 bits only provides 32 values this is limited to shifting -16 to +15 codepoints each char, this makes it rather challenging to write code with since you can only reach a max of 1/3 of the useful ASCII codepoints at a time.
u/tomxor

Here's the encoder if you are looking for a very contrived adventure: f=(s,x=96,b=16,o='')=>{for(p=0,i=0;i<s.length;){x+=d=s.charCodeAt(i)-x;p|=d+b<<((i%4^2)*5);++i%4?0:p=o+=String.fromCodePoint(p+0x10000)}return o;}; f('helloooworld')

... don't try this, seriously, you can't even get a for loop started

Saved 9 more... although it decodes at 1 bit per second !!

u/tomxor

Decoder now = 90 chars, leaving 50*20/7 = 142 chars of content yay! +2 chars
u/tomxor

To break even with 184 chars, 184*7/20 = 67 20bit chars, leaving 73 for decoder, not sure this is possible :/
u/tomxor

... I guess 1bit/s is just not good enough for the internet of the 21st century XD

Had been keeping this function around for a while but no use for it, it's just strange.
