Challenge: Add occasional mistakes like skipped characters / typos etc.
u/Polyducks

I'm struggling to understand how this works. Where have you got the function input from? Amazingly realistic!
u/Jenky

It's from (u+'') - afaik, it's basically a short/cheat way of converting anything to a string in JS :D

Also, down to 119 and whole string within canvas - https://www.dwitter.net/d/2524

was just testing...

u/tomxor

:) I actually started out with a similar idea, trying to describe it as a function... but then I got too greedy and wanted it to be exactly the same as the GEM version. This feels pretty close to the more modern logo though!

Just fixed the delay a little bit, so nothing disappears visually. (Cause that freaked me out)
