I love the design, which (separately) is printed at high resolution with vivid, accurate color! There is a sense of looking at a physical painting that I don't quite get from a screen.

The only "caution" is incidental: I'm used to a smaller mug, so have to portion out coffee accordingly. :) 🌟🌟🌟🌟🌟

Hi! I make jewelry and pretty accessories inspired by nature and especially the ocean.
I would love to help make your holiday a little more beachy 😊

#MathSky #MathArt

Hi! I turn mathematical ideas into wearable art.
I design #mathjewelry 💍 using computational software, bringing them to life through a 3D printing process (SLS nylon or lost-wax casting). Free US shipping over $99.

The way I lay out the struts it's essentially the absolute value m of the partial derivative (directional derivative in the plane of the strut); the vertical separation w is constant, so to first order the steeper the strut, the narrower it is (w/sqrt(1+m^2)). :)

Thank you!

Having most of the slices parallel to one plane does nicely accentuate how the sections vary with "depth," an effect the darker color of the cut edges heightens. :)

Thank you!

One issue with catenaries is steepness versus depth: The steeper a cross-section, the more nearly-parallel (or, "awkwardly") the slots cut the struts. The parabolas are close to the edge of that envelope at the corners, and equally-steep catenaries at the corners are not as tall. :)

It can border on a peeve when a modern image depicts a crescent moon "eclipse-style," bounded by two arcs of circles. :)

Your new shop looks great; congratulations on the launch!
