u/joeytwiddle

I knocked up something a bit closer to the video, but it cost far too many characters. (Multiple layers, from large dark purple blur to small light-purple blur.)
u/New_Core

The first line dont do anything, right? so there is still room to play around with some colors. I tried a hsl "rainbow" thing on it.

joytwiddle might try codegolf.tk

#quine that "types" itself on the screen

u/ETHproductions

The eval("...") is necessary because... well... just try with (f=_=>{...})() instead.
u/ETHproductions

I guess u/magna did a much better version already, go check his out: d/2516
u/BalintCsala

We should probably instrument anything passed to eval too...
