International audience; After accurate horizontality adjustments, a regular pattern of liquid columns formed below an overflowing circular dish can be forced to a global rotation. In this state, the whole pattern is drifting at a constant and uniform speed, with parity breaking of its elementary cells. This speed increases with the flow rate, is independent of the fluid viscosity, and increases with the value of the pattern wavelength. Possible breaking mechanisms of this global drift state into localized dilation waves are also qualitatively discussed.
