A SIGGRAPH 2013 demo from Douglas Lanman and NVIDIA of near-eye light field displays, which allow much thinner head-mounted displays that still show accurate focus and depth cues.

A short clip of the Sprint anti-ballistic missile, which was launched from a silo and reached Mach 10 within seconds. Its nose and skin glow white hot from aerodynamic heating.

A Disney Research SIGGRAPH 2013 demo of an interactive system that lets non-experts design animated mechanical characters. The user sketches motion curves and the system generates optimized mechanisms and gear trains for 3D printing.

MIT researchers show that sound can be recovered from silent video by analyzing tiny vibrations in objects such as a potato chip bag. It works even with consumer cameras by using rolling shutter.

A Polish linguist tests whether speakers of Bulgarian, Polish and Croatian can understand Interslavic, a constructed language built from Slavic languages. It shows how well they follow it without prior study.

Disney Research's demo of quasistatic cavity resonance, which uses a purpose-built room or cabinet to generate magnetic fields that deliver kilowatts of power wirelessly to mobile receivers inside.

Louis Rossmann reviews the Lenovo ThinkPad P50, covering build, thermals and throttling, then spills liquid on it to test the keyboard drainage and spill protection.

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.

A five-minute lightning demo of VisiData, a terminal tool for exploring and manipulating data. It uses two months of NYC 311 complaint data to drill down, plot points on a virtual map and save selected rows.

A two-minute time-lapse from the Kishony Lab showing bacteria spreading across a giant petri dish with increasing antibiotic doses, evolving resistance as they go.

Mark Rober visits Zipline and looks at its autonomous delivery drones, including medical and blood deliveries in Rwanda. He demonstrates how the drones' propeller design and cable-lowered delivery pod make them quiet and precise.
