Normal is part of a texture. It makes the surface look bumpy. Most of
the patterns used in pigments (bozo, crackle, granite, etc) can be used
in the normal statement

eg
box {
 -1,1
 texture {
 pigment {rgb 1}
 finish {specular 0.2 roughness 0.05}
 normal {
  wrinkles 0.5
  scale 0.2
 }
}

check the section on normal in the docs for more info
