It's Halloween! How could I resist a pumpkin for today's #inkyDays drawing?

And that's a wrap for this month of drawing, mostly from Math inspirations. All of this month's drawings and more are now posted for my supporters on Patreon and Ko-fi: https://www.patreon.com/posts/140222503

Today's Mathtober prompt is "Hexyl", and I found some pages on it over on Wolfram's math info site: https://mathworld.wolfram.com/HexylCircle.html

I decided to go with an abstraction and playing with a Chemistry inspired pattern.

Here's an in-progress shot.

Today's Mathtober prompt is "Recursion". Right away, sorting trees came to mind, and I decided to go with roots instead of branches in terms of a tree.

Here's an in-progress shot. Yes, I filled in the 'tree' recursively while drawing it by hand. I paused while drawing, and took a few in-progress shots.

Today's Mathtober prompt is "bidiminished". The diagram at the bottom of this wikipedia page served as my inspiration for today's #inkyDays drawing. https://en.wikipedia.org/wiki/Gyrate_bidiminished_rhombicosidodecahedron

Yeah, I know it's a stretch, but it inspired me to draw dancing starfish. Here's an in-progress shot.

The finished drawing is on this months posts for my supporters on Patreon and Ko-fi: https://www.patreon.com/posts/140222503

Today's Mathtober prompt is "Amalgamation", so I decided to play with nested inclusions for today's #inkyDays drawing.

Here's an in-progress shot. The finished drawing is now posted for my supporters on Patreon and Ko-fi: https://www.patreon.com/posts/140222503

Playing with yesterday's pattern again, for today's #inkyDays drawing.

Today's Mathtober prompt is "Jacobian". Looking around for info on what this could possibly mean in Mathematics, I came across this wikipedia page(https://en.wikipedia.org/wiki/Jacobi_elliptic_functions).

The patterns, partway down the page, really appealed to me so I decided to play with them for today's #inkyDays drawing.

Today's Mathtober prompt is "Odious". Which means something completely different in Mathematics than it does in general. https://en.wikipedia.org/wiki/Odious_number

I've drawing the ants in orange ink, in reference to the odious orange vandal.
