The world engines in Man of Steel are Kryptonian spaceships used to transform other planets to match the environment to Krypton’s. This makes it easier for Kryptonians to colonize foreign planets and extend their empire.
I folded this model from an equilateral triangle (I know it’s not pure, sue me) as the three legs came naturally from each point on the triangle. The legs end up really thin which is why they aren’t straight. Working with a triangle was interesting and I might try it more in the future. I know David Brill has a great horse made from a triangle and you can find diagrams online if you want to try it.
Folded from a single, uncut equilateral triangle.
