This torture/execution device comes directly from Thundercats. The mutants used it when they captured Tigra but he got away before it went off.
The Four Winds is shaped like a giant X. Along each arm one of the victim's limbs is stretched and secured with leather straps and iron bars. When activated, the gears beneath the main body of the X cause the limbs to stretch away from the torso like four small versions of the Rack. Then, when the victim believes his arms and legs can stretch no further and must be ready to rip from his body, the catapults along each arm activate. These catapults have their head at the junction of the X and their fulcra at the ends of each arm and they thus swing up from the torso and tear the victim's limbs from his body. Whether this tearing is purely the result of the mechanical force of the gears on the metal arms or if the arms are also bladed is up to the individual designer. Regardless, the result is a painful death and a terrible mess.
