For some reason, this unusual installation rekindles thoughts of long-ago chem labs of high school, with Bunsen burners all ablaze. Since this isn't a multi-burner cooktop, there must be meticulous accuracy in the design of this 'appliance'; between drilling the counter and leveling its surface, everything must be just right for each individually positioned hob.
While this isn't the product used here, Glem Progetti produces an interesting solo burner that—conditions and codes permitting—can be located at random in a room. It's called the Origine.
