for the code golfers around, I got this one down ~112bytes without the colors and less interesting noise
u/raurir

Well, I guess it's the thought that counts

Thanks for bringing up JOY DIVISION on Slack - https://www.dwitter.net/d/2108 is super well done as well.

Is there a Slack for Dwitter?

There is a general JS golf slack with a lot of dweeters in it at jsgolf.club

Nice trick with the spread operator to save a few bytes!

And the decimal Y for fake alpha, this one's packed!

Is it meant to move? I feel dumb... @.@

Sorry but this dweet was too complex to animate.There's a background color, some kind of wood texture, and 3 types of sprites rendered in a pattern.

LOL, nice :D
u/lienthealien

D: it's incredible. I still don't fully understand whats going on the begginning of the for.
u/p01

Thanks! Touching the width ( or height ) of a canvas resets it. c.width|=i=48; ⇒ Sets i to 48. Does a binary OR of 48 on the width of the canvas and resets ( it mostly clears it ) the canvas
u/sfz

redrawing the canvas and initializing i, nice!
u/lienthealien

p01 are you a wizard?? :v
u/donbright

doesnt seem to like firefox/ubuntu
u/iverjo

Hmm, why can one not do '🐸🌷☁️️'[k]? Is it simply because they are not single-byte characters?
u/p01

@iverjo: Exactly. Although I should have used [...'🐸🌷☁️️'][k] to save 3 bytes
