"Mirror, Mirror" is an interactive sound installation/performance. This work explores the fragmentation of multiple identities by using the rotation of mirrors and the reflection of human voice sounds. Mirrors are used as representations of the humans’ multiple masks. Mirrors slowly rotate and follow people(performer)'s movement by using a camera tracking system. A performer communicates with reflecting images in mirrors and creating vibration of sound. A reflection of the human figures and resonating voices comes out from speakers behind mirrors. This represents the complexity of peoples’ complicated identities and de-oriented communication within a society.
