Steampunk Gundam

Mashups are all the rage, you can't go anywhere without seeing a Star Wars this or a Doctor Who that. But just taking two or more beloved franchises or themes and mashing them together isn't enough, there's got to be a clever hook, some humor or in the case of this Steampunk Gundam by M<0><0>DSWIM, totally badassery. I want to see this thing storming the battlefield, I want to hear the chuff and joints squeal, I want to smell the coal burning. This thing is awesome.

Black Iron Giant

This colossal mech by builder Moko would be impressive enough as a static model. The color scheme, contours, detail and proportions are outstanding, but what blows my mind is how posable it is. There are action figures on the market that have nowhere near this range of motion. Usually for this flexibility there has to be serious compromises at joint density, and the figure tends to look weak at the joints, but this guy is super beefy.
