    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.

Spinning 3D model. This one is pretty CPU-heavy, gotta compromise for size

u/sigveseb

Very nice!
u/p01

It looks super clean!
u/sigveseb

is it spinning clockwise or counter-clockwise? :)
u/FireFly

shhh… it's rotating CCW I think, but cheating with the Z-axis/depth ordering means the faces are kind of haphazardly drawn :P
u/Xen

its transdimensional, you meant to do it! ;-)

Have your say regarding pixelated dweets: https://github.com/lionleaf/dwitter/pull/216

u/joeytwiddle

(The CSS in this dweet works in Chrome and Safari, but not Firefox)
u/joeytwiddle

Although I think the consensus has emerged already.

A bit clearer: s=40+90*((1-C((t/2|0)/2))**2)

for the code golfers around, I got this one down ~112bytes without the colors and less interesting noise
u/raurir

Well, I guess it's the thought that counts
u/p01

Thanks for bringing up JOY DIVISION on Slack - https://www.dwitter.net/d/2108 is super well done as well.
u/magna

Is there a Slack for Dwitter?
u/FireFly

There is a general JS golf slack with a lot of dweeters in it at jsgolf.club
