This was a not-so-impressive #tribute to this burger advert: https://vimeo.com/178939743 and here is a similar Smores advert: https://twitter.com/MachinePix/status/994279… But isn't is a shame we waste so much human effort and ingenuity on advertising (and silly dweets), instead of solving the world's problems? #capitalism #cognitivebias

I had hoped to round the edges of the bun. Alas. #food

Parallax Mountains ⛰️

These are non-repeating mountain ranges, using a similar formula used in my #JS13k game Space Huggers

The first game where I saw this effect was in Moon Patrol, I liked it a lot, it was great and also had a great music. I think it would not be difficult to recreate Moon Patrol from this Dweet.
u/andrea270872

moon patrol ate so many of my coins!! :D
u/tomxor

Pretty sure I first saw the effect in StarRay (Atari ST), I think I enjoyed the music more than the gameplay, no coins though :P
u/vain

Very cool and smooth paralax landscape

From order (in the beginning there was void) to chaos (dynamic interactions).

Stack of Hearts

u/vain

Nice!
u/vain

Btw... shouldn't "[i%5]" be "[i%6]"? Else you could save 1 char. :) What do these three points mean you used here: "fillText([... ,'" ?
u/BriSeven

Whoops, you're right. The ... is the spread operator, it splits the string in a unicode friendly way, and assigns the individual characters to the enclosing array literal.
u/BriSeven

@vain do notifications work on dwitter?
u/BriSeven

the ... next to the string is actually a special case. more generally it works on anything that implements the "iterator protocol" which is lots of stuff, but mostly arrays and array like things.
