  In a previous paper, we examined a class of possible conformations for
helically patterned filaments in contact with a bonding surface. In particular,
we investigated geometries where contact between the pattern and the surface
was improved through a periodic twisting and lifting of the filament. A
consequence of this lifting is that the total length of the filament projected
onto the surface decreases after bonding. When the bonding character of the
surface is actuated, this phenomenon can lead to both lifelike "inchworm"
behavior of the filaments and ensemble movement. We illustrate, through
simulation, how pattern formation may be achieved through this mechanism.
