Signal Visualization Playground

Seeing the Invisible Signals are the pulse of modern existence—streams of invisible energy that shape everything from the songs we hear to the satellites that guide us. Yet, for all their importance, they remain unseen. We feel their effects, depend on their precision, but rarely witness their behavior. The Signal Visualization Playground changes that. It’s a realm where physics becomes art, where data takes on shape and color, and where
