The full experience (six chambers, every diagnostic and the complete Hg-80 journey) is available to commission or license for museums, galleries, science centres and visitor attractions.
Hg-80 is the small liquid-metal being carried in Mercury’s signal. With no fixed shape of its own, it gathers itself into a bright little body, rides a quicksilver skiff, and follows your hand from gate to gate.
Hg-80 does not speak for the planet—it listens. Heat and cold, impact, shrinking stone, reversed sunlight and the solar wind all become signals. In the Signal Game, you help Hg-80 catch the messages Mercury cannot hold.
Each gate turns one physical condition on Mercury into something you can feel and test. Enter in any order. Run the diagnostic inside a chamber to record an actual response—not a personality label.
Visited gates brighten in their own colour. Recorded diagnostics gain a stronger double ring. The Signal Game is always available from the orbital hub and every chamber.
