Not all slider combos are error free, but at this point I'm done debugging. https://turtletoy.net/turtle/dde69185e7#firstSplit=6,split=2,margin=6.01,sateliteR=7,connectionWidth=2.6,hatching=0 https://turtletoy.net/turtle/dde69185e7#firstSplit=5,split=2,margin=6.01,sateliteR=7.1,connectionWidth=1.4,hatching=0 https://turtletoy.net/turtle/dde69185e7#firstSplit=5,split=2,margin=6.01,sateliteR=7.1,connectionWidth=1.4,hatching=1.3

oh christmas tree

An implementation to resemble a concept I saw in a piece by u/KennyVaden at https://www.reddit.com/r/generative/comments/146sxqo/disruptor_r_code/ https://turtletoy.net/turtle/80f5254064#shapes=4,layers=7,distributionBySize=1,postitsPerLayer=500,directionVariation=60,sizeVariation=150,border=3,sizeRandomness=2.1,onlyOutLines=0 "Post-it" is a registered trademark owned by 3M

I just made it configurable a bit, even though i have no clue what is going on :D

I have ported most of "ln, The 3D Line Art Engine" by Fogleman (@FogleBird) to javascript, so it can be used on Turtletoy. Not all code is ported and not all code-paths are tested: probably there are still (a lot of) bugs left. This Turtle is a port of the example: https://github.com/fogleman/ln/blob/master/examples/skyscrapers.go

Fork of https://turtletoy.net/turtle/68ef188d1f - removed the PoissonDisc usage - added the grid that is used in this turtle https://turtletoy.net/turtle/abbc1557a1 by @reinder This grid allows two shapes; squares / hexagons, which are randomly spit and distorted. Examples: - Hexagons: https://turtletoy.net/turtle/deca53a32d#seed=1,grid=15,randomDistortion=0,spacing=0.15,splitChange=0,baseShape=1,lightAngle=2.1 - Squares: https://turtletoy.net/turtle/deca53a32d#seed=1,grid=15,randomDistortion=0.09,spacing=0.15,splitChange=0.41,baseShape=0,lightAngle=2.1

tree rings

A circle of points connected by springs. They are constrained to a slowly growing circle. When they get too far from their neighbors, they split. Each point leaves a line behind as it moves.
