In this talk we will report on the effect of a spatiotemporal forcing applied on Turing stripe patterns under spatial resonance. An unexpected symmetry-breaking phenomenon, leading to hexagonal lattices, has been found in experiments performed with the photosensitive CDIMA reaction, forced with light passing through a travelling mask. We will propose and analyse a
theoretical framework which allows the understanding of the experimental observations.
