Every 3D object is just a grid of voxels. Each cell is either on or off, giving 2cells total arrangements.
The total number of possible shapes is incomprehensibly large. Somewhere in that space is, for example, a hammer. The most efficient boat turbine ever designed. A model of your future home. A 3D scan of a face you haven't met yet.
Hit Random Combination — you'll get noise. But in theory, keep hitting it long enough and you'd eventually see any object imaginable. Don't hold your breath.
