    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.

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

Golfed to fit

u/marquisdegeek

Storing the gfx data like that is sweet! So nice to see if without obfuscation!
u/BriSeven

if you deduplicate the symmetry, rotate it (so that it is 8 rows of 16 pixels), and prune out the two rows that then are just zeros... we can shave the graphics data all the way down to 鰜鹞廾皶㜷彟
u/BriSeven

which would be worth it if you can find a way to undo all that which isn't more code than the characters we save
