That's a pretty cool idea, Noel. How would you apply something like that? Direct application? Stencil? I'm not well versed in such things.
Not to pee on your idea at all, because I do like it, but I'd always imagined Stormtroopers as the ultra clean-cut types. Kind of like the SS, I guess. (There are so many parallels between the German military and the Empire it's not funny. It's a good thing no one takes that relationship too seriously! )
*As a total side note, I'm really not fond of what the Clone Wars Animated Series has done with the clones, Kamino, and clone culture. I sort of understand why they did it, being a kids' series, the marketing aspects, and all that, but I'm rather stuck on Karen Traviss' concept.*
