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.

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 short video of a Microsoft Surface multimedia coffee table, with a pointer to making a homemade multi-touch screen. It shows the original touch-table concept.

A live performance at AGDQ 2014 in which Super Mario World is made to execute arbitrary injected code, running other games like Pong and Snake on the cartridge. It is done through a TASBot feeding precise controller inputs.

SethBling uses Super Mario World glitches to inject and run Flappy Bird code on an unmodified SNES, entering it purely with controller inputs. It was the first time a human completed this kind of exploit by hand.

Intrinsic Gravity is a real-time demoscene production by Still, made with the Tooll tool for Under Construction 2014. It is a black-and-white op-art animation with a soundtrack by hoffman.

A recording of the TASBot block at Awesome Games Done Quick 2017, where a robot plays games via tool-assisted speedruns, including Super Mario 64 and Portal on an SNES via arbitrary code execution, and ending with a Twitch Plays segment. It showcases console exploits and creative hardware hacking.

A demo of the 8pen, a gesture-based keyboard replacement for touchscreens that lets users enter text by moving around a circle. It is meant for phones, remotes and game controllers and mimics handwriting.

Lyle Bickley of the PDP-1 restoration team tours the 1959 DEC machine at the Computer History Museum and plays the original Spacewar! He covers its graphics display and the MIT student programs written for it.

Karl Sims's 1994 demonstration of evolved virtual creatures: block-bodied creatures whose bodies and controllers are evolved through selection, mutation and recombination to swim, walk and compete.

A tool-assisted speedrun of Pokemon Yellow on Game Boy Color that uses glitches and frame-precise inputs to make the game execute an arbitrary program. It was later obsoleted by an improved run.

Hugh Jeffreys tears down the iPhone 13 and assesses its repairability, showing how Apple ties parts like the display and Face ID hardware to specific devices. He demonstrates that swapping parts, even genuine ones, can disable features.
