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
