And if you have seen the intermission screens and wondered how these work: They run my software info-beamer (https://info-beamer.com/hosted) on a Pi3 in each Hall. Basically those intermission information screens are written in Lua. My info-beamer software uses both hardware accelerated video decoding as well as OpenGL(ES) to make things run smoothly. I'll release the complete Lua source code early next year. If you want to see how these worked last year, take a look at https://github.com/info-beamer/package-32c3-screens
