There is disclosed an apparatus comprising processor and memory and a three-dimensional object bearing at least two, unique fiducial markers, the processor executing instructions which cause the processor to generate a three-dimensional environment including a user interface element for interacting with the three-dimensional environment, detect rotational movement of the three-dimensional physical object using the at least two unique fiducial markers, and update the user interface element within the three-dimensional environment based upon the rotational movement of the three-dimensional physical object.
