Genius.

Wow. This is very clever
u/rodrigo.siqueira

Now I can't look at city buildings without thinking about this. See https://en.wikipedia.org/wiki/Tetris_effect The Tetris effect (also known as Tetris syndrome) occurs when people devote so much time and attention to an activity that it begins to pattern their thoughts, mental images, and dreams. E.g. People who have played Tetris for a prolonged amount of time can find themselves thinking about ways different shapes in the real world can fit together, such as buildings on a street.

@rodrigo I think I have The Dwitter Effect, or "Dwitter Syndrome" :D i'm not even joking
u/sigveseb

Nice idea! As an added bonus, if you leave it running for a while you get a graph of the prng bias for free :)

t?o.frequency.value=300*1.06**'994577542225997544457799552'[t*6&31]:o=(a=new AudioContext).createOscillator(),o.connect(a.destination),o.start() is 4 bytes over but sounds better.
u/joeytwiddle

Excellent! #audio #music For anyone who wants the sound to stop, just scroll down to the next dweet then hit Reload.
u/joeytwiddle

It sounds good enough with 200 instead of 99 but +1 over
u/alien

is there anyway to stop this!!! ?

Awesome!
u/iverjo

Tetris! Any way we could slow it down?
u/FireFly

Very nice! (i&7)*8 → i%8*8 should save you two bytes, btw
u/farter

@iverjo in fact at first i tried, but if it's slowed down, you'll see some wrong but minor behavior, due to saving bytes. and @FireFly thx, and the two bytes allowed me to solve one of them!
u/Renaud___

I am trying to do anything like that since 4 days ... with 180 char, cant golf it... full respect farter :)
