    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.

Inspired by Google's loading bars animation. It could be golfed further but I was just looking for enough room to put a nice comment

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
