    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.

damn damn damn... wonder what is the space between the two = after for(c.width| if I replace it by a normal space it kills the dweet :|
u/danny@hille.dk

+(+!+[]+[+[]]) is a slightly less verbose way to write 10, withou using any digits
u/danny@hille.dk

for(c.width|=ﾠ=ㅤ=+(+!+[]+[+[]]) ,x.scale(ﾠ,ﾠ);--ㅤ; ) x.fillRect(S(t)*(ﾠ+ﾠ+ﾠ)+ﾠ*ㅤ+ﾠ+ﾠ+ﾠ+ﾠ,ﾠ+ﾠ+ﾠ+ﾠ,ﾠ/(ﾠ/ﾠ+ﾠ/ﾠ),ﾠ+ﾠ)
u/danny@hille.dk

or less obfuscated : for(c.width|=a=i=+(+!+[]+[+[]]),x.scale(a,a);--i; ) x.fillRect(S(t)*(a+a+a)+a*i+a+a+a+a,a+a+a+a,a/(a/a+a/a),a+a)

Wow... it took me a bit to get the idea... cool trick!

Will throw 7 if the decryption works correctly. #slow
u/katkip

it lags so much
u/f8f82804

it should be possible to optimize the modular inversion and exponentiation, but it would probably go over the character limit

You've reached the end.
