A typical tombstone feature might comprise e.g. a carved pine tree (2) on a stone base (1), with inset differently colored lights (3) on a concealed wiring circuit, connected to a power unit (4) based on a solar panel with back-up battery, recharged when necessary by the panel. In other forms, the decorative feature, e.g. the figure of a bird, may e.g. be rotated by a small concealed motor, or a small electric pump may power a feature based on a closed water circuit.
