    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.

thx to @Jenky for mouse golfing ideas. 须 = whiskers, mouse tells its position by c.width/c.offsetWidth or c.height/c.offsetHeight

This is nice, but not really in line with the concept of a dweet ;)
u/lionleaf

Nice! Is this the first interactive dweet?
u/PhiLho

A bit of cheating, but fair enough, as long as you are not imitated by lot of people... :-D

This seems to be broken atm. Does not respond to mouse movements.

If you change the "🐳" character to "X", they will run faster. If you change it to number "1", they will run on their knees. If you change it to "6", they will run jumping.

Thank you all, this is one of my best. :)
u/Polyducks

What trick are you using here? Is the code minified into escape codes?
u/Polyducks

Omg killedbyapixel! I saw your byte battle last night!
u/Toby

this is beautiful quite apart from the dweetness!
u/KilledByAPixel

thank you! you can replace eval with throw to see the code.
