Flickr newcomer mad_a0 recently exploded onto the scene with this awesomely detailed minifig-scale tank.
Very cool, certainly, but what sets this tank apart is that mad_a0 has built a fully detailed interior. Most LEGO tanks are lucky to fit a minifig driver, much less components like a removable engine.
The exploded view itself is a study in excellent presentation. See more photos on Flickr.
