Visualize a mech that is fundamentally a sphere, with its lower half ingeniously transforming into four symmetrical, sharp- pointed triangular legs. Focus on the fact that these legs are not additional appendages but are formed directly from the sphere's structure. They should appear as if the sphere itself splits and the material of the lower half flows seamlessly into these legs, maintaining the sphere's surface texture and design continuity. The visual should emphasize the mechanical elegance and innovation of this transformation, set against a clean, futuristic background that enhances the mech’s form and highlights its advanced technological nature
