Beter than double_illuminate: Backside illumination.
It's activated by providing a second value for the diffuse component of 
the finish as follow:
diffuse 0.5 0.4

To keep the end result acurate, the summ of the two values should stay 
less than 1. Part of the incident light is diffused back and another 
part is duffused through the surface.
