A 3-minute demo of a tiny IOCCC 2012 winning C program that simulates fluid dynamics in an 80x25 terminal, using any text (including its own source) as input. The video shows the simulation running to Handel's Water Music.

Casey Muratori follows up his refterm proof-of-concept, a GPU-based terminal renderer, with a second part covering memory usage, glyph sizing and correct Unicode and VT handling. It is built to show that a terminal can be fast and correct without heroic effort.

A short film about the Erlang language, showing telecom systems built from lightweight processes and demonstrating hot code swapping. It is an edited version of the original Ericsson video.

Tom Scott shows a full-size real-life emoji keyboard built from 14 keyboards and over 1,000 hand-placed stickers, covering all of Unicode 8.

Big Clive tears down a cheap eBay digital caliper, explaining its capacitive linear encoder and measuring its quiescent current. He finds it surprisingly accurate and repeatable for its price.

In the finale of Double Fine's Devs Play, speedrunner SMK demonstrates glitches and exploits that skip entire sections of Psychonauts while Tim Schafer and the dev team watch. The developers react to and discuss the bugs as they appear.

SethBling performs the first credits warp in Super Mario World on a real SNES console, a glitch that plays the ending without beating Bowser. The run relies on pixel-perfect positioning and tools such as a helper ROM hack.

Cosmo's 22:38 Ocarina of Time speedrun, performed live at AGDQ 2013. The runner uses a complex exploit to skip much of the game.

A demo of a raycasting 3D engine built entirely from in-game mechanisms in vanilla Factorio 0.17. It renders simple 3D scenes, producing a new frame every 45 game ticks, with the video sped up to compensate for low UPS.
