We discuss the dynamics of colloidal rollers staying close to a planar wall in a viscous fluid. Available experimental and numerical data show that an array of such rollers exhibit spontaneous front formation, followed by the development of an instability and eventual break-up. Hydrodynamic interactions between the rollers seem to be responsible for the observed behaviours. We study the basic physical mechanism which leads to the instability and pattern selection in this system.
