Practical Engineering explains Mechanically Stabilized Earth, where layers of reinforcement make soil strong enough to hold heavy loads, shown with a sand structure supporting a car. It notes that MSE walls are everywhere in infrastructure.

A five-minute SuperMemo demo of incremental reading: importing a Wikipedia article on nutrition, extracting passages, making cloze deletions and finishing the item. It lists the keyboard shortcuts used.

Bisqwit builds a Doom or Duke Nukem 3D style software-rendered 3D engine in C from scratch, supporting non-Euclidean geometry. It covers vector rotation and portal rendering with sped-up, tool-assisted coding.

Sebastian Lague explores an ant-inspired algorithm and simulates ant and slime mold behavior, using compute shaders. Source code for both simulations is available.

A TV show about Ivan Sutherland's 1963 MIT thesis software Sketchpad, which ran on the TX-2 computer. It shows a light pen drawing, constraints, snapping, scaling and object-style graphics, foundations of GUIs and CAD.

MinutePhysics explains that computers store brightness nonlinearly, so blurring and blending colors in raw RGB gives wrong, dark results. It shows why mixed colors, such as in gradients, look off.

The SIGGRAPH 2005 demo of dual photography from Stanford, which swaps the roles of projector and camera to render a scene from the light's point of view. It includes the reveal of a hidden playing card.

A seven-minute demo from the author of Notcurses, a C library for text user interfaces. It shows the 2.3.0 release, which adds Sixel and Kitty bitmap graphics integrated into its multiplane character-graphics model.

Blender Guru's beginner tutorial series, in which you model, light, texture and render a donut while learning Blender's core features. This is Part 1 of the Blender 3.0 version.

A 60fps capture of Future Crew's 1993 MS-DOS demo Second Reality, one of the best-known pieces of the demoscene. It runs about 16 minutes of real-time graphics and music effects on PC hardware of the era.
