    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.

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

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

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

I had implemented so many more features, like a nice gradient while drawing, but had to scrap a lot to get it in 140 characters... :( DwitLonger please!

Neat! At first thought it was a lopsided <3 :P
u/Xen

its all in the codegolf, you'll learn some shortening tricks by looking around here, t?x.lineWidth=3:x.t(960,540)

Ooh, that's a really neat trick, thanks! And here I was, so proud of my for loop :p

there will be a messaging system shortly, will come in handy for shaving that last pesky byte

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!
