    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)

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!

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
