    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!

Outstanding. Your motivating me to up my game. How much of your work is trial and error about what looks cool vs actual engineering?
u/cantelope

artfarnaa, thanks. it's mostly just educated guesses. Most of my dweets start as a pretty concrete idea, then I draw from experience and do my best to fit the idea into 140b. Sometimes I'm successful, and sometimes not. :)

very similar to the original, but showing its ability to appear to travel endlessly in one direction.. also changed the spacing and rect size a little.
