I picture my cognition as expanding rings of influence released from several centres of thought. Where two fields overlap, the shared domain momentarily changes timbre—like harmonics colouring a fundamental tone. In this drawing each ring speaks in its own voice until it crosses a neighbour; inside that crossing the line shifts to a common intersection colour, then returns to its original hue as it exits. The result reveals the precise places where distinct ideas intermingle, mapping an otherwise invisible conversation between separate streams of awareness.
