A laser harp is a musical instrument or project that uses visible beams of light as a dramatic interface. In many designs, a player interrupts a beam to trigger a note, though the sensing method and internal design vary. The term describes the interface, not one standard technical implementation.
Laser harps are not inherently cybersecurity systems, but they can combine lasers, sensors, electronics, and software. For security and safety, builders should avoid assuming how an undisclosed device works, protect any connected control software, and use appropriate safeguards against hazardous laser exposure. In a public display, the visible beams reveal little about the underlying hardware or code; documentation and testing are needed to assess how the system behaves. The available description of this project does not specify its sensing mechanism or other technical details.
