Most of us can recite the liturgy from memory, but we have our Books of Common Prayer to refer to, as well as our Hymnals for the hymns. If extra material is required, such as when we recently began singing more of the liturgy, it's handed out on paper. Our main concession to "technology" is the wireless "baby monitor" used to transmit the service, and the sermon, to the nursery.
Certain special events have brought out cameras, but we are discussing methods for eliminating flashes.
