In this paper we present Shoggoth, a 3D graphics based program for performingnetwork music. In Shoggoth, users utilize video game style controls to navigateand manipulate a grid of malleable height maps. Sequences can be created bydefining paths through the maps which trigger and modulate audio playback. Withrespect to a context of computer music performance, and specific problems innetwork music, design goals and technical challenges are outlined. The systemis evaluated through established taxonomies for describing interfaces, followedby an enumeration of the merits of 3D graphics in networked performance. Indiscussing proposed improvements to Shoggoth, design suggestions for otherdevelopers and network musicians are drawn out.
