    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.

Fantastic job! Love the use of the cos(t-i) aka backface culling as alpha value of the fillStyle to sort the splats and skip clearing the whole canvas. That was THE killer optimization to fit in 140 chars.

Does it JS or another language?
u/fusty

Wow . . . how?

It would be amazing if you could post an expanded, commented version along with your 140 character versions on this site.

I'm completely new to all coding and just found out about this amazing community; how on Earth do these symbols code for a globe?
u/hg

oldspork These symbols are just what unicode decides his binary data can best be represented as in text. The real magic is the charCodeAt part of their code.

Spritegen! Generates 48 random sprites each time the dweet is run (make a change to rerun the dweet)

I love this!
u/alien

wait WHAT !!
u/alien

D: What is going on here!! how
u/iverjo

How does it work?
u/FireFly

It's a dweetification of an older sprite generator of mine. The idea is to take a "mask" of 0..1 floats and filter a grid of random numbers for when num<mask. In this case the mask is based on euclidean distance from centre. This is done for half the sprite, and then the other half is just mirrored
u/FireFly

(You could also view it as flipping a biased coin for each mask value, with the bias given by the mask)
u/FireFly

The same principle would work just as well with larger sprites too, and more exotic/interesting mask shapes. The same rid of random numbers could be applied to different masks, or to an animated mask, to produce an animation between sprites, too!
u/nystrand

so cool!
u/joeytwiddle

Awesome. I love it. Every single one looks like a space invader!
u/iverjo

Interesting technique. Thanks for explaining :) Also, I agree with joeytwiddle
u/jick

Got a link to the original sprite generator?
u/FireFly

I never really wrote it to be shared, so it's all hardcoded and with really ugly code. I put together this animation though: https://twitter.com/FireyFly/status/80072288…

Simple, but effective! Makes me want to play 8-bit games again.
