Pareidolium by Rafael Lozano-Hemmer is an interactive mirror made out of clouds of vapor that ascend from the water basin. The fountain uses computer-controlled ultrasonic atomizers, placed under the reflecting water pool, which produce the plumes of cold vapor. As a visitor looks into the water, a facial-detection system extracts their image and creates an ephemeral likeness. The portrait becomes tangible, almost breathable, only briefly, then disappears in turbulence.
There are many other interactive artists creating similar interactive mirror in different medium, such as wood block or wool. However, I am particularly drawn into this one because of its transient quality and the way it merge and disappear is very soothing and elegant. Fog creates a sense of mystery that really draws audiences in to look at the installation and gives it a more self-reflective characteristic.
