This is very heavy on my laptop! Remixed here: #4841
u/joeytwiddle

Very nice though. It plays tricks on my eyes, seems to be always growing.

Sometimes dwitts gets heavy here also scrolling down the list.. most times it help to copy the share link and look at it alone, but yea this one can be heavy, running lots of filters and "gCO"'s

This may not work in FireFox at the time of writing, because of the new ** operator (exponential). Works in Chrome though :)
