This machine can flow,
     moving over, around, 
     & through.

Skin conforms to the contours
     of musculature.

Muscle binds to bone,
     muscle that thickens
     and lengthens and ripples
     and pulses.

Bones that flex and recoil.

But that machine can flow --
     over, around, and through.

It can cause air to pop
     and water to slosh
     and earth to tremor.

It crawls through liquid,
    slices through gases,
    and slams the solids,

but can move over, around,
    and through.
