Harvey 5000 Mime-Mobile
Described as "The most beautiful thing you'll never see," the Harvey
5000 Mime-Mobile is an invisible lagomorphic locomotive device created by a troupe of mimes. It takes the combined imaginative force of four mimes to conjure and sustain the construct while a fifth mime pilots the vehicle.
