    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.

Check out the new top feeds! There's now top of the week, top of the month, top of the year as well as top of all time! #text #new_feature

u/lionleaf

And yes, I usually browse the #text hashtag looking for something to remix when I announce new features :D This was a great one, u/veubeke !

Very nice :) Keep up the good work, @lionleaf

MORE disks >:) #beesandbombs

stop being so good
u/katkip

i love your beesandbombs dweets
u/pavel

I call fill just once, the black bits are a single connected shape that zig-zags, the messy edges are hidden offscreen.
u/pavel

I use 1/(1+9e9**x) to smooth step but even rows step twice in one cycle which is done by adding (j|t)%2 as offset.
u/pavel

In hindsight ~~x+(x%1)**9 is better for multi-smooth-step animations.

Removed the second repeat call to make it shorter, as suggested by jylikangas. Used a bolder rectangle character, as suggested by joeytwiddle here: d/9591 #short #default #unicode

u/jylikangas

If you use 111111111 you get a 3D version with less bytes. :)
u/Qwitter

nice!
