    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.

Ask you friends: Does it spin clockwise or anti-clockwise? ;)
u/darrencearnaigh

Anti-clockwise, because history - :P https://en.wikipedia.org/wiki/History_of_tri…

This is one of the coolest takes on the starter dweet I've seen in a while!
u/Xen

impressive
u/j0bit

Hypnotic
u/darrencearnaigh

Aye, that implied double-helix in the movement is pretty cool.
u/hope4tg

I like how if you stare at it long enough, you see shifting concave diamonds. Very cool!

Beautiful!
u/iverjo

Nice! Looks like it's a remix of https://www.dwitter.net/d/1231
u/Cistoran

It is! I'm new to the site and wasn't sure how to tag it as such. My apologies!
u/Xen

you can live edit the code of any dweet and a 'remix' button appears, click that and it posts with a link to the original ;-)
u/lionleaf

No worries, I've got you sorted ;-) Just make sure to use the remix feature next time. Nice remix, didn't immediately recognize it as such.
u/J2D28U

Damn... I'm new as well and this exchange has kept me here!
u/Xen
