FortNine explains how Harley-Davidson ended up in decline, from a narrow lifestyle niche and an aging customer base to the pandemic hitting a company already in trouble.

The Map Men explain why British place names are so hard to pronounce, tracing it to layers of Viking, Anglo-Saxon, Celtic and Norman influence, with a pronunciation guide.

Matt Parker of Stand-up Maths asks whether a country's reported land area accounts for hills and mountains, working through how surface area depends on the resolution of elevation data. It follows up on a question from a viewer and work by researchers who measured it.

Huygens Optics shows how DIY photon sieves shape a laser's wave front, explaining how they differ from zone plates and how aperture count affects the focal point, with time-resolved visualizations of the diffraction.

John Lin reveals a rewritten voxel engine demonstrated in a Crystal Islands scene, with much finer voxel detail, fast collision, fracture and path-traced global illumination.

James Lambert demos a MegaTexture-style technique running on real Nintendo 64 hardware, built for an N64Brew game jam. It streams high-resolution textures onto stained-glass scenes on the console.

Epic's Unreal Engine 5 tech demo set in the Matrix universe, with Keanu Reeves and Carrie-Anne Moss. It moves from a cinematic to a playable car chase through a large detailed city, with a behind-the-scenes look at the rendering at the end.

Red Bull and the Dutch Drone Gods follow Max Verstappen's RB20 F1 car around Silverstone in a single FPV shot using a custom drone that accelerates to 300 km/h in about four seconds. The video also covers the year of development behind the drone.

Acerola explores building a shader that turns games into ASCII art, walking through techniques such as brightness mapping and edge detection to see whether it looks good.
