Dare to Be Negative!
Do you remember analog photo negatives? I still have some, tucked away deep in the archives. I always found them eerie and uncanny. Humans turned into zombies with black teeth. Burnt orange, weird cyan and violet everywhere. But what did I expect? We don't have an intuition for addition or subtraction of colors. Would you "expect" red and green adding up to yellow? The exact opposites of our usual, friendly red-yellow-green-blue are uncommon in the real world. I once tried to create […] -

Circles to Lines (2026)
Circles and lines - that sounded manageable. So, this was one of my first attempts at reviving descriptive geometry. A circle on a sphere is projected into a circle in the equatorial plane under stereographic projection. But if the source circle contains the North Pole, the projection ray in this point becomes tangent to the sphere and parallel to the equatorial plane. Thus circles containing the North Pole are projected into lines - circles with infinite radii. The drawing shows this […] -
Drawing With Code
What does it even mean? I see two main ways of drawing with code: 1) going for a representation of a thing you have in mind, or 2) using an algorithm and elements of randomness to surprise you. Representational I have code-drawn Lissajous curves with code - from a picture in mind before I started. I saw the curves as built from wires as thin as possible, or as thick metallic tubes. I have been lucky that I mathematical objects can be compressed so well into code. It would be way more […] -

Vertical exaggeration (Cartography 🗺️)
Vertical exaggeration is a scale that is used in raised-relief maps, plans and technical drawings, in order to emphasize vertical features, which might be too small to identify relative to the horizontal scale.

Circles to Circles #2. A Friendly Death Star.
My art should speak for itself, as an abstract geometric drawing. But if you are so inclined, you can decode the math. Mathematics shows up twice: In the thing I am depicting, and in the techniques I am using to draw it geometrically. The series Circles of Circles is about stereographic projection of circles onto circles, and I am using orthographic projection as a tool. In a sense this is "orthographic projection of stereographic projection" Circles to Circles #2 by elkement 2025, […]https://elkement.art/2025/05/22/circles-to-circles-2-a-friendly-death-star/

Circles to Circles #1. On Descriptive Geometry.
I am not a hoarder. I parted with school memorabilia long ago. When I started reading books on e-readers, the remaining books felt like an odd time capsule. They were not representing my reading self anymore. So, I got rid of most books, too. There was one exception: I still have my high school Descriptive Geometry books. "DG" was taught for the two last years of high school, in grade 7 and 8 (age 17 - 18). I remember it as pure delight - learning how to depict three-dimensional objects […]https://elkement.art/2025/05/16/circles-to-circles-1-on-descriptive-geometry/
