    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.

Mouse spiral paint #uncompressed as wished by u/ximavus

u/rodrigo.siqueira

My favorite trick here is onmousemove=e=>T=e:x , so you can get coords from T.x and T.y later. And the letter T prevents the "ReferenceError: X is not defined" initialization bug, since T is a previously defined variable.
u/rodrigo.siqueira

You can compress even more by changing the random component from i*i%255 to i*i%w but the image will be a little bit lighter.
u/rodrigo.siqueira

My second favorite trick here is the ternary operator: t?(...when t=0...):(...when t>0...)
u/ximavus

Thank you!
u/ximavus

Actually those tricks are awesome especially the onmousemove one

Awesome circle thingy #circle

And yes I did write it on my own its not a copy of @KilledByAPixel's mod circle
u/lewdev

tbh, I was initially suspicious. I suppose you're referring to this: d/34354

yes the mod idea was from d/34354 but I didn't copy paste or smth

Paint that works in fullscreen too

u/cantelope

👍
u/ximavus

here's a 32 character golf: change the c.width/innerWidth and c.height/innerHeight with 3.4
u/ximavus

I checked how much it is and its actually 3.386243386243386 but 3.4 is pretty close
u/lewdev

I didn't want a hard-coded version because this solution is much better than this d/34332 which uses getBoundingClientRect to find the accurate position of your mouse no matter the size of your canvas. But I'll keep that in mind for future dweets.
u/ximavus

ok
