They're made of... wood

Brickshelf user egunnero gets an awesome wood effect by mixing brown and reddish brown. I've always loved the potential of the new colours for subtle shade variations but this is probably the best use of it I've ever seen.

We don't need no Stinkin' Cabs!

Tim David recently made a very nice cab-less SD45. The wheels are probably my favorite bit as well as the side vents and grilles. My only complaint has to be the herald, but the fact that it's brick built makes up for it. As you can see in the gallery, he also made a GP38-2B which, too, is simple yet awesome.
