Scene 5 is a deliberate attempt to make use of balance by forcing a diagonal line of
visual interest through the image, starting at the table on the left, then travelling left to
right through the speaker in the center, and on to the window in the upper right. The
line you will notice travels through the vertical and horizontal thirds, creating visual
connectivity. We also get a measure of depth in the shot as this POV gives us some
natural foreground and background object separation.
