An apparatus and method for generating 3D graphics objects utilizes algorithms to generate the objects when driven by audio events. In one embodiment a "hydra" object has branches that are recursively generated. Parameters used to algorithmically generate the object are controlled by a control signal driven by detected events in an audio signal. Additional algorithms include a phase plot using audio parameters. A generalized system includes an audio analysis block for generating audio control signals utilized by object generation, objects selection and object placement blocks to generate 3D objects.
