This document describes a new concept for museums called "treasure boxes" that use beacon technology and the physical web to provide an interactive experience for visitors. The boxes contain exhibits and use beacons and the Particle Photon development kit to trigger an opening motion when visitors' phones detect the beacon. A website connects to the Photon to control the box and provide additional content. The treasure boxes aim to provide an engaging experience for visitors while overcoming limitations of existing mobile app-based approaches. Challenges include maintaining the boxes and scaling the supporting web presence.
