Two-frequency parametric oscillation of silicone film excites waves of two wavenumbers, that combine into exotic superlattices. Here, we describe a transient superlattice pattern transition from initially stable hexagonal waves. The hexagons break to form DNA-like structures, which transform to rhomboidal structures. Afterwards, a transient two-hexagon state forms that eventually breaks to again form a DNA pattern with a longer wavelength. We invite the viewers to observe these exotic patterns and appreciate the rich physics of mode interactions in Faraday waves.
