About This Project


August 2014

Size: Approximately 7’ x 9’ x 4 ½’

Materials: Polyester Drafting Film, RGB LED Strips, Sound, Speakers, Microcontrollers, Audio Equipment


Portal is a sculptural installation combining sound, colored light, and constructed forms designed to create a zone for repose and relaxation.


Each crystalline form contains colored lights that slowly pulse and cycle between blue, bright violet, and indigo, as well as a speaker for transmitting sound. The sounds are layered sine-wave frequencies composed in harmonic relationships. Using monaural and binaural beat-patterning techniques, the sounds pulse rhythmically back and forth between each shape and across the viewer in interlocking patterns. These patterns can assist in inducing calmness and relaxed brainwave states.


The goal of this project is to create a space and generate an ambience that can enable a positive mood-altering experience.


The sounds employ the use of drones combined with rhythmic pulses to illicit shifts in attention, facilitate anxiety reduction, assist in trance-like states, calm the nervous system, smooth or tune brainwaves, and assist feelings of well-being.


The color and light patterns are designed to combine synergistically with the sound for similar effects. References to sacred spaces such as stone circles, new-age iconography, mythic and sci-fi symbolism, are intentional in the creation of the ambience generated by Portal.
