Can anyone give me hints on how to realistically simulate wrinkled, 
golden foil ? I'm making a model of NASA's Cassini spacecraft (an early 
version can be seen at http://www.mmedia.is/~bjj/povstuff/spacecraft/ ) 
and these things are often wrapped in golden stuff to protect them from 
the harsh environment of space. I have experimented with the normal, 
ripples and turbulence keywords but have not been happy with the 
results.

There are some photos of what I'm after at 
http://saturn.jpl.nasa.gov/gallery/spacecraft/index.cfm , in particular 
http://www-pao.ksc.nasa.gov/kscpao/images/large/97pc1098.jpg , note the 
'circular' golden object near the center of the image.

Note that this looks rather like wrinkled aluminum foil so if someone 
has realistically simulated that it should solve my problems (the only 
difference is the color).
