Bruce Hauman presents Figwheel, a ClojureScript tool for live, interactive development with hot code reloading. He explains the main ideas, demonstrates how it works, and shares tricks for getting the most out of it.

Elias Martenson presents his Emacs-based workflow for building a web application (the Potato chat platform) with Common Lisp on the backend and ClojureScript on the frontend. He demonstrates SLIME, Paredit, CIDER and debugger-driven interactive development. The talk is 79 minutes and was given at Emacs SG.

A short demo of interactive AI live painting in Krita using the Stable Diffusion plugin, where canvas changes update the generated image immediately. It uses an LCM sampler for speed and needs a high-end GPU for the interactive feel.

Johnny Chung Lee shows how infrared light pens and a Wii Remote can make a very low-cost multi-point interactive whiteboard or tablet display. Software is available for download.

A one-minute satirical clip of a person trying to pass as a normal guy with the line "Did you see that ludicrous display last night?". It parodies awkward small talk about sports.

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.

Chris Urmson's SXSW 2016 talk on Google's self-driving car project, covering 1.3 million self-driven miles and the gap between hype and reality. It shows sensor visualizations and playbacks of hard situations the cars met, and discusses failures such as the low-speed bus collision.

Fons van der Plas introduces Pluto.jl, a reactive notebook for Julia that tracks references between cells and re-runs affected cells when code changes. The talk was given at JuliaCon 2020.

Technology Connections gives first impressions of using an Onyx Boox Max2 e-ink tablet for productivity, including using it as an external display. He shows what the device can and cannot do.
