Coffee-Powered Stargate

Let me open the Stargate of Diffraction for you, once again! This is as close as I ever got to a plain scientific visualization: No 3D effects, just the intensity of diffracted radiation as a function of position in space. If you use a sun catcher - a film with a diffraction grating - the peaks in such images are where you would see bright blurry spots of rainbow […]

$Collage of a print design template and mockups of a coffee mug printed with diffraction curves - the intensity of diffracted light over angle, for different colors in the spectrum of visible light. The design is rolled up adn printed on the cylindrical surface of the mug so that the angle is exactly represented by the position on the mug's surface. It looks like a wavy rainbow-colored fabric on black background. The image shows the design on top (duplicated - as if white light would shine from opposite directions onto a grating in the center) of four views of the mug from different perspectives. Artwork created by elkement with custom code in 2023, adapted for mugs 2026.$ $elkement and her art. elkement reflected in a framed poster of her diffraction art: Stargate of Diffraction$

Still writing Visitor patterns and manual tree recursion in Java?

Part 4 of Functional Optics for Modern Java shows how the Focus DSL turns this into fluent, composable paths:

.departments().each().employees().each().salary()
No reconstruction boilerplate. Just declare what you want.

We build a complete expression optimiser using the Focus DSL.

Having gone through the batch, it seems that, (as the Smiths never sang): "Some Prints are Tighter than Others"

I will leave the model as it is and folks can make their own accommodation one way or another.

Oakee doakee... Got the prints back. Sphere retention is a bit too tight with these dimensions. It takes significant force to engage sphere. Will adjust octagon dimensions for greater accommodation.

Note: Material is black photopolymer resin. SLA process. No sanding.
