The motif is the button of an elevator.
Finished like real elevator buttons - so much so that
you'll be tempted to push them - they comprise acrylic glass in the
style of an elevator button, a luminova dial ring glowing softly in the
dark, and a metallic dial.
With the colors and signs on the glass, they represent the
destination, positive feelings, and the scene you anticipate to see when
the doors open.
