    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.

nice, Gabe! i'm glad you're using the remix feature and making experiments, modding other dweets and referencing then at the same time. on dwitter soon we learn more then we thought we could. keep coding, you're welcome!

Nicee
u/Ath0r

Thanks! It's the first time I've tried, so probably I missed a lot of tricks to reduce characters... Any feedback or tips are welcome! :D
u/13thptr

b is unused so you can remove it :)

nice dweet btw

Thanks a lot for the suggestions, @13thptr! Indeed, I forgot to remove the unused b and the characters you remove by avoiding the definition of p is also very nice :)

Searching for f(x,y,t) this time. If you have more patience then add operators, parens and increase string length in the slice.

heh, i missed that opportunity

Clever concept, like some old tv grasping at transmissions.
u/DataMeta

Haha, Xen
u/tomxor

Nice analogy :) like a TV into the computable universe, infinite channel! (sorta)
u/21medals

Why the space in between each character of E?
u/tomxor

Because -- and ++ are assignment operators, and I cannot allow those on loops variables X and Y. It's basically cheaper in chars to pad with spaces than test for this with a regex.
