    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.

Was wondering how the shape evolves as the constant in C(99*i++) changes.

u/AnnanFay

Change 2e3 to 99 for a more vigorous experience.

Alternatives are: 33 chars using Wallis product but *very* long time to converge. 24 chars using Newton-Raphson if sin & cos allowed.

6.3 is pretty much 2*PI. Putting fill() where it is causes it to fill the pacman in 9 times but saves a byte. Using with saves another 1-2 bytes.

#FFEE00 is also supposedly the official Pacman colour.
u/silver_bear

Wow, you're quite a bit more advanced than me. Very nice! :)
u/lionleaf

Cool! Similar to one of the really old dweets by u/iverjo : d/312 . :)
u/21medals

you can save 2 bytes by moving "w=500" to the moveTo()
u/AnnanFay

You can also replace 2*w+w*i+++t*-w%w with 2*w+w*i++-t*w%w for 1 byte, you can save 2 bytes by adding i=2 and w*i++-t*w%w which puts us at 135 bytes
u/AnnanFay

One thing I'd like to fix is the rate which pac-man bites down at. It would be nice if it synchronised with the squares.

Oh, why do you use kanji characters as variables?
u/AnnanFay

The kanji are so I don't accidentally redefine a variable which something uses. For example there's code which does t||(_=c.width) so if I use _ it would break the code. It will break stuff which uses these kanji, but right now this is the only dweet using them.
u/fujimotos

Nice. I didn't know that they are valid variable names...

Slideshow v2.1: A minor bug fix. Previous versions no longer work because of dwitter improvements. Good news is we can now use }{ in dweets for one time code.

See https://github.com/lionleaf/dwitter/issues/2… for details on the improvement.

First time using setTransform, seems useful. .524/(a>3?5:1) is shortform for Math.PI * 2 / (a>3?60:24).

u/AnnanFay

Hmm, just noticed a few things. Would be smaller without with(x) since there's only two method calls. Also we don't need the 0| after the slice because the division will cast for us. So that's 7 characters.
u/akm

You can also remove some parentheses and the l variable: for(c.width|=a=12;a-=3;x.fillRect(-9,6,18,-a*50))x.setTransform(r=C(θ=Date().slice(13+a,15+a)*.524/(a>3?5:1)),n=S(θ),-n,r,960,540)
u/silver_bear

Impressive that you managed to fit both seconds and real hands. Seems I lack a bit of syntax creativity. Nicely done! :)
