Watching MSNBC tonight and got curious about the "big board". I was trying to figure out if it was some kind of Linux app or a windows application on a white-labeled Surface Hub. Turns out, it's a web app! Mapbox + D3.

Which also tracks with some of the design decisions for the web app itself. Gestures are notoriously a pain on the web, and this software doesn’t use gestures for anything beyond drawing annotations. Even things that would make sense as drag gestures are explicit buttons.
