Automaton Mashup 🦠 (FLASHING WARNING)

Show more comments…
u/cantelope

ima just start education everyone, the photosensitivity thing is EXCEEDINGLY RARE AND ONLY IN PEOPLE AFFLICTED BY EPILEPSY, AND TYPICALLY INVOLVES HIGH-CONTRAST FLASHING AT AROUND 3Hz (3 cycles per second). NOT JUST RANDOM BLINKING PIXELS OR COLORS. thank you
u/cantelope

yes extreme, mass paranoia bothers me
u/neimad

About 1.2% of people have epilepsy. So if there are 100 visitors to this site, at least 1 of them could be affected. I think it's worth having a disclaimer as 1.2 out of 100 isn't an infinitesimally small number. If 1000 people visit dwitter, 10 of them may be affected and that's not nothing. It's not paranoia, it's empathy.
u/Joachim

Very cool dweet
u/Xen

love it!, i'm thinking click to play flag if this is deemed problematic?
u/tomxor

Nice, reminds me of those silly movie scenes where they try to illustrate automation by spawning a bunch of GUI windows... except with cellular automata :D
u/andrea270872

Very demo-like! Cool.
u/andrea270872

About the epilepsy, perhaps there could be an option that a dweet can start "frozen" or "running". It would help me as well, because on some mobile devices, a script sometimes blocks my browser... just saying ;)
