Golfed the time-waster

Less charming, I know, but at least it fixes the typo
u/akm

Oh my goodness, I just noticed my typo. I like the trick you did for the font!

I have been golfing on this for some weeks
u/danny@hille.dk

unfortunately I lost the origins of the code, but it was a post on codepen
u/danny@hille.dk

The depth trick was lifted from one of u/cantelope dweets
u/tomxor

Terrain Terrain! Pull Up 🚨
u/pavel

Whoa!
u/Qwitter

that is relaxing
u/UEZ

what is the purpose of -t%1?
u/danny@hille.dk

gets the fraction if t: Try writing ´throw t%1` in a dwitter editor
u/danny@hille.dk

Well i guess it's leftover code from the depth calculation golf :-) doesn't seem to do much now :-)
u/UEZ

Yep, removing it can save some bytes without any effect...^^
u/UEZ

Btw, looks very nice. :-)

Looks nice with n=_=>S(t*_)*99+166 and R(n(1),n(2),n(4)) as the colour

This is almost what I see when I close my eyes in the dark.
