could've shaved off a couple more bytes and have it work in Safari too:

slowly is how they always steal it :-(

Octobuffering Infinite Balls

Got the plumbing done, but spent only a little time to try to find a nice pattern. Please remix!

u/donbright

lol unfortunately this went way over my head... could you explain what it is?
u/magna

Rendering subsequent frames to a circular list of 8 off-screen buffers and pasting the buffers to the main canvas. Creates an "infinite sprites" effect.
u/New_Core

the effect can be visualy seen how it works at https://www.dwitter.net/d/401 ;)

I can't find any instance of this being done before, but I'd be surprised if I was the first. Not as elegant as u/metamero's version, but shorter! Several earlier #quine dweets happily include the declaration of u. #throw #golf

u/metamero

pretty sure i saw or done this before hehehe but is a nive one to have on your page. you see it is a js quine not a "strict dwitter quine", since you have to delete function u(... . and nive job golfing d/11826 . as far as i know, so far, this is the record =]
