    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.

credit to Amir because he made the dweet; shoutz to Apex because his dweet inspired me, and big big thanks to AnnanFay who helped me make this dweet..

It's cool, but isn't linking an external script cheating?
u/dogspace

its the only way really

u/meaniningOf42 that's the point ;p

u/FFS2309

I wonder why your script on pastebin has to be that long ? Does it do anything other than just recreate the dwitter environment for the actual code to run in? I'm asking because I did some script loading test already ( d/5992 ) and my code worked without recreating the environment.

Dweet slideshow. Shows a new random dweet every 9 seconds starting at older dweets. Some dweets will break it since all changes are in global scope.

This is the best one because it shows them all!! I'm trying to figure out a way to extract which dweet number is playing at a given time (maybe using the debugger?)
u/AnnanFay

Thanks :) Developer Tools -> Network tab will display the requests. The latest request will be the one playing.
u/AnnanFay

There's a 150 byte version which displays IDs as error messages. (async I=>eval(T.L==I?T[I]:(T.L=I,T[I]=((await(await fetch(V=0|Math.random()*I*100)).text()).match(/u\(t.*([^]*?) }/)||(T.L=T))[1])))(1+t/9|0) throw V

I thought I'd see if I can calulate PI in 140 chars. Math.PI is 3.141592653589793, which is 15 decimal places. 15 decimal places is precise enough to calculate the circumference of the solar system (including Pluto) with an accuracy of a meter. The formula is Nilakantha's from the 15th century. You could also just print 245850922/78256779 but doing that doesn't seem much better than just printing Math.PI.
