Remember the "distortion field"? This feature is similar, but it is an 
actual patch that implements a warp which does the same thing to a 
pattern. The syntax is simple:
warp {
    displace_warp {PIGMENT}
}
Here is an image of a displace_warped checker pattern(left) and a 
gradient pattern(right). The displacing pigment is a bozo pattern with 
an automatically generated color_map.
