Editing Parallax (section)

== Demonstration ==

# Set up the white board, either propped up or against a wall, and use the tape to mark a spot 10 feet in front of the board. Put the stand on the marked spot, and then mark another spot 10 feet further along the same line and mark it. This will be where the volunteers stand.
# Have two volunteers come up. Have one stand on the left side of the marked spot and use the laser pointer to point at the star. Mark the spot where the laser lands on the white board, and then have the second volunteer do the same, but stand on the right side of the marked spot. Mark their spot on the white board.
# For a hands-on event, give everyone at the table a pencil and paper and ask them to draw the scenario as you draw it, and provide the explanation. Otherwise, for a stage show, go straight into the explanation.
