BMW kidney grilles

This is a sculpture of the evolution of the kidney grille, a signature feature of the BMW brand. Even though The kidney grille has obviously changed over the many years, but you don't notice the slight changes from the current model to the next, as they are so similar. But here you can see them all, And as they are all layered they create some really nice shapes and forms which gives great inspiration.
