Dan Romik:
MadHat — a New App and Language for Mathematical Writing (software demonstration)

I will give a demo of MadHat, a new desktop app and LaTeX-style markup language I’ve been developing for authoring documents and presentations with math-rich content. MadHat offers instantaneous compilation as you type, and generates documents with dynamic elements such as animated slide transitions, videos, collapsible and expandable sections, and more.
