TakeOff is a fork of ShowOff, a Sinatra web app that reads simple configuration files for a presentation, it was written by Scott Chacon and it lives at https://github.com/schacon/showoff. TakeOff implements Airplay, a gem that streams content into an AppleTv - and soon to any computer running an AirServer, this gem was written by Bruno Aguirre and is maintained at https://github.com/elcuervo/airplay. The goal is to stream your presentation's slides to a remote AppleTv/Computer hooked up to a projector without the need for physical cables and while being able to browse through your notes without it being noticed.
