    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.

First version of permalinks in place! Please test it :) More work to be put into making it easier to discover the rest of dwitter from a permalink.

Cool, that almost looks like 3D!
u/lionleaf

This doesn't work on my Macbook with chrome for some reason.
u/New_Core

can it be the translation? if you put 0 in last number of translation and set the last number in code to 500, do you see something then,, or remove the translation and keep the 500 at the end of code,
u/lionleaf

Turns out any font size above 250 doesn't show up. 250 works fine though. Nice effect!
u/New_Core

ah ok

You can now enter more than 140 characters while writing a dweet! (But you can't post anything longer than 140 characters)

u/iverjo

Sweet :) I remember removing maxlength=140 in my dev console when creating dweets at arkt.is/t/ ^^
u/PhiLho

Yes, that's what I did here as well... :-D Ah, except I get an alert dialog on each character beyond 140! Not very practical to type. The red counter should be enough...
u/PhiLho

And apparently we can now safely replace semi-colon with newline, even on Windows! (they counted as two chars, previously...)
u/iverjo

Yes, that alert should be removed. Luckily, one can suppress it in FireFox by checking the checkbox inside the alert
u/lionleaf

Ooops, I never got the alert for some reason. And I didn't see this before now. Should be fixed now.

this tunnel looks so clean!

Thanks :) My aim was to create a vertical camera tilt effect. I ended up just moving everything up and down. Kinda resembles tilt ^^
