If you like history and LEGO, Hunter Erickson is a builder you need to check out. His most recent build represents a violent slice of the late years of the ancient Roman empire. The builder gives a very detailed description on Flickr, so make sure you check it out.
Besides being very well posed in an immersive battle scene, the minifigs are quite realistic in their design. The little autumn forest on the other side of the diorama is more than just a background though — if you look closely, you can see it serves as cover for a handful of Germanic archers. And the trees are quite well built as well!
