    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 don't see the boat. Chrome on macOS.

Ah, I see it on Chrome on Windows though. Nice!!!

font maybe to big for macOS, try change it to 5 cm or so, might work

This works only Fullscreen: you can hook and unhook the ball with your mouse.

Hijack S/C instead of X/Y to prevent the initial reference error
u/New_Core

I dont get that Hijack to work.. I made a push ball but it has also reference error before it works so I will not do a remix.. here is code
u/New_Core

t?c.width|=0:a=b=X;c.onmousemove=e=>(X=e.offsetX,Y=e.offsetY);D=X-a,E=Y-b,Math.sqrt(D*D+E*E)<50?(a-=D/9,b-=E/9):0;x.arc(a,b,50,0,7);x.fill()

a quick paralx idea, ofcourse would been nicer filled in colors ;) wonder if it can be shorten enough for that.

i literally laughed out loud playing this
u/joeytwiddle

Brilliant :D
u/Woodmouth

Hmm, there is actually quite a bit of space left. Can anyone make it follow the mose?
u/Woodmouth

Or wait... that would require a lot actually, nvm, i doubt it will be feasible.
u/joeytwiddle

I could get it to chase the mouse but could not keep the edge detection: https://www.dwitter.net/d/2495
u/Woodmouth

The slow turning is exactly what i was thinking of. I've already asked once, but why not again? Is anyone able to compress the last 12 characters in joeytwiddle's 2495 with the slow turn addition?

reduced it by about 15 bytes in case you want to try to do something else with the extra room: c.width|=0;for(i=16;i--;)x.ellipse(1e3+300*S(t+i/9),500+50*C(t+i/9),160*S(-i/2)+160,50*S(i/9)+5,1.6+S(t)/2,9,0,7);x.stroke()
