The spectrum around you is crowded - phones hunting for known networks, wearables advertising themselves, mesh routers gossiping in the background. None of it is visible, and the tools we have are built for analysis, not atmosphere. I wanted an ambient display driven by the spectrum.

In this system, each node senses, passively listening for the wireless traffic that betrays nearby devices. It coordinates, sharing what it sees with the other nodes. It expresses, driving a layered animation engine where device counts, traffic bursts, proximity, and movement through the space all become inputs that shape color and motion.
