The final #ArtAdventCalendar post: My most involved artwork of 2025: 3D Lissajous Figures, constructed exactly from their 2D projections. Watercolor pencils on canvas. #SciArt #MathArt See the evolution of this painting step-by-step on my blog: elkement.art/2025/09/17/l... Happy Holidays!

Geometric watercolor pencils drawing on stretched canvas: Three overlapping Lissajous figures defined by combinations of sin(t), sin(2t), sin(3t), and a third “3D” view as an orthographic projection. The lines are used as a tesselation of the drawing surface and colored in the style of stained glass. The painting has been completed as has been varnished.

alright, mastodon seems to really like this so let's see how bsky feels: "Coprime Mandala" - all numbers relatively prime to n for each radius n #math #mathart #dataart

A circular graph of coprimes. Each radius n represents the numbers 0 to n - 1 arranged in a circle like a clock, with 0 at the top. A dot is filled in if the number is relatively prime to n (their greatest common denominator is 1). This yields a curved pattern of stripes that start from the bottom and folds up toward the 0 o'clock position. There are "missing" white bands at a half turn, at third-turns, and at quarter turns. The top half consists of nearly-vertical repeated patterns while the bottom half consist of almost-square "cells"

The same diagram as before with a voronoi triangulation, so instead of a dot at each number there is a cell that is shaded lighter the higher the gcd of it is with the band it's in. This leads to a skewed checkerboard pattern with stripes radiating on the outside.

#ShowMeYourKnits #mathart 🧵 After I broke into two-color brioche, I had a brainwave that I could do this really cool thing as a knit #cowl. It was two years before I finally made my first try, shown here. Explanation and photos to follow; keep an eye on main and background colors. 🌈 🧶 #knitsky

The second session in the afternoon at the Bridges #MathArt conference starts with Tuan Dung Do, who speaks about "Visual Illusions in the Hyperbolic Plane." (archive.bridgesmathart.or…) Some illusions might work better with their tool: cs.uwaterloo.ca/~bdo/proj…. (1/3)

An extension of the Hermann Grid Illusion to the Poincaré disk model of the hyperbolic plane.

An extension of the Scintillating Grid Illusion to the Poincaré disk model of the hyperbolic plane.

An extension of the Rotating Snakes Illusion to the Poincaré disk model of the hyperbolic plane.

#ArtAdventCalendar Day 3 Poinsot's Gyroscope, 2025 Physics of the spinning top again - its motion visualized via these dancing cones! The yellow one is moving, and its axis is also the axis of the gyroscope. Axonometric projection, watercolor pencils #SciArt #MathArt #PhysicsArt

Mathematical art based on the physics of the gyroscope, using methods of descriptive geometry. Poinsot's construction - motion of a thin gyroscope visualized by looking at three cones that dance with each other. Watercolor pencil and watercolor markers on watercolor paper mounted on foam board. By elkement 2025.

I am using traditional descriptive geometry and watercolor pencils to turn functions used in physics into cathedrals from stained glass. #MathArt #SciArt

Collage of five geometrical drawings - colored in the style of stained glass with watercolor pencils. Orthographic projections of functions used in physics, constructed from their 2D projections: Cones related to the theory of the gyroscope, Lissajous Figures, spins and stereographic projection, a mathematical tower from a spherical harmonic function.

Day 1 of #ArtAdventCalendar Translucent Heart, 2025. 3D Lissajous Figures, constructed traditionally from their 2D projections which in turn have been constructed by dividing a circle. #MathArt #SciArt Graphite pencil construction, colored with watercolor pencils, A4 watercolor paper.

Scan of a geometrical artwork: Construction of 3D Lissajous Figures from the 2D projections, using ruler and compass, following the rules of orthographic projection. Two self-similar Lissajous Figures are connected to form a ribbon. The 3D ribbon is yellow and the 2D projections are green-blue and blue-violet, respectively. By elkement 2025.

Augmented reality, old school: The Higgs field is everywhere ... so I am overlaying a geometric construction of its potential with a watercolor painting of a pond! First experiment with watercolors on canvas (primed with DIY watercolor ground) #MathArt #SciArt #Physics

Watercolor painting on canvas: A pond surrounded by meadows and trees superimposed with a geometrical construction of the Higgs potential thats looks like the top part of a fruit juicer. By elkement 2026.

I did it! I created a Lindenmayer system in Excel. It accepts custom symbol and value definitions, starting strings, multiple rules, and the pattern coordinates are automatically repositioned and resized during the VBA run. #CreativeCoding #Fractal #Koch #L-system #MathArt

"Translucent Heart" New canvas print in my store! store.elkement.art/produc…. I always extend the drawing with a digitally mirrored and distorted version - to make it "drip off" the sides of the canvas. This time, I let this melted edge appear on the front! #MathArt #SciArt
