In the early days of staged performances when there was no electricity, the light on the performer was cast by burning chalky lime in pots at the front of the stage. When performing downstage close to the pots, you were considered to be in the “limelight.”
While we have electricity these days to power the lights, sound systems, and multimedia projectors, never forget that the audience is coming to hear you. YOU are the number one visual in any presentation. While you are in the limelight, your connection to the audience, your energy, and your message are more important than any other visuals you may use.
