Very interesting post and technology. The new 4D holographic video systems on the market could possibly be used in this way in churches to engage the audience. Imagine interactive maps showing the journeys of Jesus or Paul, or the spread of the Gospel across the globe, or visually showing local demographics by zip code of where the church members live and where they are impacting their community. Who knows what other great creative ideas church leaders will come up with to leverage this technology as a tool in worship and teaching.
