undertoe is a fully immersive, interactive environment which traces the invisible vibrations of participants' footsteps visibly into a pool of water above their heads. Wherever the viewer steps, water ripples out from directly above where their foot landed. Soft light passing through the undulating water illuminates bands of light and dark on the space's walls and floor. As more participants cross the threshold into undertoe, their waves disperse and dissipate over time, interfering with one another, and emerging as ever more complex waveforms.

undertoe is the experience of walking on water and watching yourself from beneath the surface. It re-presents the imperceptible currents of vibration our bodies unwittingly produce; these are sensed by the piece and transduced into water - a medium that slows down and re-embodies this resonance as perceptible. Our sweeping effects slowly creep across the water’s surface, and perform potential interactions with other bodies in space.

undertoe is an experiment in material memory, shared affectivity and the realm of the intangible.

currently a project being pursued by Nathaniel Stern, undertoe was originally conceptualized
in collaboration with Greg Shakar at the Interactive Telecommunications Program, 2001
