摘要: A display apparatus including a light box upon which a display piece can be removably positioned and illuminated from behind. The display piece carries a machine-readable tag from which a tag reader in the light box may obtain identifying information. A central processing unit in the light box selectively energizes a digital audio player and an aroma diffuser in response to the identifying information obtained from the machine-readable tag by the tag reader.
