3D movies give no hint of relative importance of or interrelations between different exact invariant solutions. Some physical insights on this are gained by studying

Energetics of the flow

E instantaneous kinetic energy of the fluid
I   power input by the shearing motion of the walls
D  instantaneous bulk dissipation rate
