    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 was trawling the interwebs for fun and leisure and found this sprite sheet http://legacy.gamebuino.com/forum/viewtopic.… and of course i thought of dwitter :-)

wow amazing encoding
u/danny@hille.dk

Thanks mate, I didn't really know how the encoding was done, so i came up with this solution function makeMagicString(data, width){ let buf = ''; let str = '' data.forEach((o,i)=>{ if(i%width===0 && i){ str += String.fromCharCode(parseInt(buf,2)); buf = ''; } buf += o?1:0; }) str += String.fromCharCode(parseInt(buf,2)) return str; }
u/danny@hille.dk

where data is an array of 1 and 0 ex: [0,0,0,0,0,1,1,1,1,1,0,0,0,0,0, 0,0,0,1,1,1,0,0,0,1,1,1,0,0,0, 0,0,1,1,1,1,0,0,0,0,1,1,1,0,0, 0,1,1,1,1,0,0,1,1,1,0,1,1,1,0, 0,1,0,0,0,0,1,1,1,1,1,0,1,1,0, 1,0,1,1,0,0,0,1,1,1,0,0,0,0,1, 1,1,1,1,1,0,0,0,0,0,0,0,0,1,1, 1,0,1,1,0,0,0,0,0,0,0,0,1,1,1, 1,0,0,0,1,1,1,1,1,1,1,0,0,1,1, 0,1,1,1,0,0,1,0,1,0,0,1,1,1,0, 0,0,1,0,0,0,1,0,1,0,0,0,1,0,0, 0,0,0,1,0,0,0,0,0,0,0,1,0,0,0, 0,0,0,0,1,1,1,1,1,1,1,0,0,0,0]

I know it's not the most elegant solution, but I stick to the mantra "If it works, it aint stupid" :-)

you can kinda make it a perfect loop by prepending t%=9; or for a more dramatic effect: t=T(t/3);
