    u(t) is called 60 times per second.
    t: Elapsed time in seconds.

    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.

Smaller uncompressor, only takes about a second to boot up!

Here's the compressor code... $="for(c.width|=i=9;i--;)x.fillRect(400+i*99+S(t)*300,400,50,200)";n=[...new Set([...(';'+$)])].join(o='');for(v=i=0;(q=$[i])||i%4;++i)v+=q?n.indexOf(q)<<i%2*5:0,i%2?(o+=String.fromCharCode(((i%4==3?55:54)<<10)+v),v=0):0;throw 't?eval(O+="'+n+'"["'+o+'".charCodeAt(I/2)>>I++%2*5&31]):I=O=""'

From my testing it can do up compress up to 224 characters of code if all of the unique 32 characters are used!

Swapping the ternary statement for }{I=O="" at the end saves one more char.
u/tomxor

But this will only work on a new dweet
u/tomxor

Really need a larger charset though :/ I think 64 should be enough for most, which bumps it up to 6 bits, but that requires a lot more code to extract, might still be better than 184 though?
u/tomxor

Nah, before even considering extra decompression code, 6 bits with 32 dictionary barely provides 192 chars, as soon as you start actually filling the dictionary with more you quickly go under 140 encoded chars. I think you hit the best balance for this method.
u/KilledByAPixel

i think 5 bits is the sweet spot, it is definitely tough writing code that only uses 32 chars but maybe we can see some programs that would not otherwise be possible

This is how you can create these UTF-8 things, to store ~200 bytes of js code

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

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')
u/tomxor

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