Following on from the discussion in povray.general, here's an image using 
the slope pigment with the direction vector pointing at the camera:

texture{
    pigment {
      slope {
      <-3,0,1>
      }
      color_map {
        [0.00 color rgbt <1,1,1,0> ]
        [0.10 color rgbt <1,1,1,0> ]
        [0.15 color rgbt <1,1,1,0.8> ]
        [0.65 color rgbt <1,1,1,1> ]
        [1.00 color rgbt <1,1,1,1> ]
      }
    }
    finish{ ambient 10 }
  }
