Ancient Calligraphy 📜

u/magna

Lovely!
u/KilledByAPixel

Thank you! This is a becoming a fun series to work on.
u/rodrigo.siqueira

This form of artistic writing is known as 書道 (shodō), meaning "way of writing". Nice strokes of Cursive Script (sōsho) of an ancient Hiragana, Katakana and Kanji calligraphy artwork. It even includes the Hanko (red stamp of artist's signature) in the bottom! Unfortunatey I was not able to translate this, but it seems to be some kind of poetry from the Han Dinasty.
u/hvianna

The spreading ink effect and the red stamp are really nice touches!

Lost At Sea 🏊‍♂️

u/UEZ

I like the very smooth waves :-)
u/taupelink

wow!
u/pavel

Very nice vibe. You can do x.fillStyle='#025'+j for the fade to avoid the low rez.
u/pavel

Hm your sub-pixel trick works even at 1:1 rez... neat

#sphere

u/donbright

thats cool... how does it work?
u/joeytwiddle

Very nice! #halftone
u/f8f82804

u/donbright: I used the parameterization from d/5600. I like it a lot because it keeps fairly even density of dots on the surface. It's based on cylindrical coordinates where each point is at a different vertical level and the points spiral around. The key is that not all values of i result in drawing a dot. We drop the back half of the sphere with C(a) >0, but we also implicitly drop points where s*i-i*i is negative
u/donbright

thanks... fascinating...
