Mathober 2021

Prompts are at the bottom of this post and the information for Mathober is here. I used ink and code for this daily practice and really enjoyed seeing everyone’s posts on their blogs and twitter. Let’s plan for next year. Prompts will be generated in September of 2022. Ink: Day 1 – Multiplicity Day

Mathober 2021
triangles with circles drawn at the vertices nested within each other to a shared center

Prompts are at the bottom of this post and the information for Mathober is here. I used ink and code for this daily practice and really enjoyed seeing everyone’s posts on their blogs and twitter.

Let’s plan for next year. Prompts will be generated in September of 2022.

Ink:

Day 1 – Multiplicity

Code (click image to open):

Day 1 – Multiplicity

triangles with circles drawn at the vertices nested within each other to a shared center

Day 4 – Curve

sin and cosine waves on a dark canvas

Day 7 – Cycloid

a blury mess of blues and purples

Day 10 – Snub

a mixed up tiling

Day 13 – Hole

a wave of circles in 3d space

Day 16 – Arbelos

arbelos overlapping with hexagons within the circles

Day 19 – Knot

a knot in the dark

Day 22 – Triangle

what looks like an iris, but make of many faint triangles

Day 25 – Parallel

parallel lines

two fingers and 5 with one diagonal in the corner

Day 31 – Macron

a dash in white on a black screen

flammy circles alternating black and orange

Day 5 – Order

two triangle cut in to many smaller triangles

Day 8 – Complex

streaks like a turquois comet in the dark

Day 11 – Zero

Day 14 – Rule

a game of life with a random graph with many vertices on a circle

Day 17 – Variation

a line with variation points above and below going from purple to pink

Day 20 – Parametric
