Spontaneous pattern formation in physical system is governed by the competition between intrinsic and extrinsic length scales, causing the emergence of complex spatiotemporal profiles. The authors demonstrate that spatial nonuniformity sets Faraday-wave patterns in motion, and clearly identify the zigzag and drift dynamics in their wave crests.
