In this paper, we discuss the results obtained by means of the EGGS (Elementary Gestalts for Gesture Sonification) system in terms of artistic realizations. EGGS was introduced in a previous edition of this conference. The works presented include interactive installations in the form of public art and interactive onstage performances. In all of the works, the EGGS principles of simplicity based on the correspondence between elementary sonic and movement units, and of organicity between sound and gesture are applied. Indeed, we study both sound as a means for gesture representation and gesture as embodiment of sound. These principles constitute our guidelines for the investigation of the bidirectional relationship between sound and body expression with various strategies involving both educated and non-educated executors.
