Perturbed plane Couette flow containing a thin spanwise-oriented ribbon undergoes a sub-critical bifurcation at Re approximate to 230 to a steady three-dimensional state containing streamwise vortices. This bifurcation is followed by several others giving rise to a fascinating series of stable and unstable steady states of different symmetries and wavelengths. First, the backwards-bifurcating branch reverses direction and becomes stable near Re approximate to 200. Then the spanwise reflection symmetry is broken, leading to two asymmetric branches which are themselves destabilized at Re approximate to 420. Above this Reynolds number, time evolution leads first to a metastable state whose spanwise wavelength is halved and then to complicated time-dependent behavior. These features are in agreement with experiments.
