DIY Perks builds a realistic artificial sun for dark winters, using a powerful water-cooled LED, a satellite dish reflector for near-parallel rays, and a scattering layer to mimic the blue sky. The video explains the optics behind why most lamps do not look like sunlight and shows the build and its results.

Scott Manley uses a realistically scaled Kerbal Space Program setup to show why dropping something into the Sun is far harder than it sounds. It demonstrates the need to cancel orbital velocity.

A short first look at Dasung's 25.3-inch Paperlike 253 e-ink monitor, edited from the company's own Weibo reveal video. Price and release date were not yet known.

A Samsung-backed viral demo that builds a fast computer from 24 256GB MLC SSDs in a RAID 0 array and shows the throughput results.

A 1991 NeXT promotional video that stages a head-to-head programming contest between a NeXT computer and a Sun workstation. It shows NeXT's interface builder and object-oriented tooling producing an application far faster than traditional UNIX development.

Linus Tech Tips reviews the Dasung Paperlike E-Ink monitor, asking whether an e-paper display makes sense as a computer monitor. The video covers its slow refresh rate, eye-comfort claims and day-to-day usability.

Sunspring is a sci-fi short film starring Thomas Middleditch. Its screenplay was written by an LSTM neural network trained on sci-fi scripts, and the team shot and edited it in 48 hours.

A two-minute 2008 clip from Sun's Fishworks team in which Brendan Gregg uses DTrace to show disk latency spiking while he shouts at a rack of drives. Bryan Cantrill narrates the demonstration.

A 1995 Sun Microsystems film about the Self programming language, a prototype-based Smalltalk relative, showing its live, graphical programming environment.

A 1994 video from Knight Ridder showing a concept for a tablet newspaper with a rounded-corner rectangular touchscreen. It was reposted by Matt Novak of Paleofuture.

A short demo of Sun Microsystems' Looking Glass, a 3D desktop GUI concept for a future operating system.

Markus Kayser's Solar Sinter project video shows a machine in the desert using sunlight and sand to 3D print glass objects. It is a short demonstration of desert manufacturing from renewable energy and local material.

A short look at CoeLux, an artificial skylight that recreates the scattering process that makes the sky look blue, producing a convincing illusion of distant sun and depth.

An animation presenting a non-standard helical or vortex model of the solar system, in which the planets trail the Sun through space instead of orbiting in flat circles. The model is a non-conventional view that the author says differs from standard diagrams.

A Discovery Channel computer simulation of a large asteroid impact on Earth, showing the scale of the devastation. It sits in a broader context of early Earth impacts and the moon-forming collision.

Physics Girl shows a vortex phenomenon (a falaco soliton) that can be reproduced in a pool on a sunny day. Two vortices are created with plates and made visible with food coloring.
