    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.

Incorporated improvements from 21medals and myself. Spent extra characters fixing the chomp rate so pac-man eats every square.

c.width|=τ=6.3,y=S(t%1*τ*2) puts this down to 134 bytes. Thanks to joeytwiddle.

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

Brilliant! The network tab!

Every time I scroll through this dweet, I think "Funny, don't remember giving an awesome for this dweet". :D

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.
