I received an email about these guys a few days ago and instantly fell in love with their look. These are called the Diamond Ninja War Machines and are the creation of Tony Gil. Not only will these guys wreck you with their sick martial arts skills, but they'll also do a bit of urban design work while they're at it.
These started out as Munny figures from Kidrobot and evolved beyond that platform. I love the outstretched arms that each hold a repurposed Bent World Spray Can toy. You can tell these took a lot of work, but the design is so clean and simple that it's almost deceptive. Check out more of Tony's ninja figures (including an upside down hanging ninja that will blow your mind) at his website below.
