When two waves encounter each other, they make an 'interference pattern'. Crest and trough create a resultant wave of greater, lower or the same amplitude in this superposition and these periodic pulses form natural patterns of beauty which we can discover in manifold natural circumstances. The crest and trough series features physical works inspired by these interference patterns in waves.
