Abstract
A drum assembly includes a drum, a stimulus processor assembly and a light pattern display generator. The drum includes a drum shell that at least partially defines a drum interior. The stimulus processor assembly receives a stimulus, generates an input signal, and converts the input signal to an output signal. The light pattern display generator receives the output signal from the stimulus processor assembly. The light pattern display generator generates a light pattern display in response to the output signal. Additionally, the light pattern display generator projects the light pattern display at least partially within the drum interior. The light pattern display generator can include one or more of an animation laser, a hologram projector and a lumin disk. The stimulus can be generated by the drum or by a source remote from the drum.
