    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.

Amazing!
u/UEZ

When I add c.style.filter=blur(5px)contrast(105%) and compress it the result isn't the same. A bug in the compressor?
u/UEZ

Or decompressor?
u/danny@hille.dk

the only thing hat changes is that 'code' wil now contain you eval(unescape(escape... and unicode chars
u/danny@hille.dk

and in this example, the code wil execute with some 'undefines' because [i%128] and code is only 127 chars - eval(unescape(escape󨼮󬽴󮝬󩜮󩭩󫍴󩝲󟜧󨭬󭝲󚌱󭭷󚝣󫽮󭍲󨝳󭌨󜜩󙼻󩭯󬬨󮌮󩭩󫍬󤭥󨽴󚌰󛌰󛍷󟝩󟝣󛭷󪝤󭍨󟜷󝼷󛍷󚜻󪜭󛜻󮌮󩭩󫍬󤽴󮝬󩜽󙼣󜍦󞌧󚝸󛭦󪝬󫍔󩝸󭌨󨽯󩍥󦽩󙜱󜬸󧜬󪜬󜬲󜬭󤼨󪜯󜼳󜼪󤼨󭌯󪜩󚽓󚍴󛝩󛼹󞜩󚜪󭼯󝬫󥌨󭌫󪜩󚬴󝌩.replace(/u../g,'')))

Thanks Danny, I meant not the code result but the gfx result.

yep, as did I :-) in dwitter the variable 'code' is a reference to the source code of the dweet itself, your compressed source differs from the uncompressed. and as this dweet is s a quine (code taht write out its own source), the results differs
