Light was used to create a wavelength‐dependent interfacial tension gradient at a liquid/liquid interface to induce an interfacial flow; thereby generating droplet motion in the direction opposing the gradient. This “the chromocapillary effect” is described by D. Baigl et al. in their Communication on page 9281 ff. The liquid droplets can be controlled using light along the trajectories of any shape (e.g., a heart) with good precision.
