Installation, 2022 — HOT•BED Gallery (WAITING ROOM), Troy Glow Exhibition, Center for Mediterranean Architecture (Un-Natural Mat(t)erials Exhibition)
Light Pebbles is a dynamic light installation by Yael Erel and Avner BenNatan, including the light pebble series - a series of light objects that project swirling light projections of seemingly three dimensional light structure. Within each pebble, a reflector revolves, casting light beams off of its specular surface and transcribing its geometry in light. The transforming light drawings draw the viewer into a meditative gaze. Different Reflector geometries generate different light patterns.
The pebble’s were developed with assistance from Renssealer Polytechnic Institute (RPI) reseach students Cooper Myer, Eileen Dong, Gunnar Thuss, and Owen Lawler and with support from RPI Fabrication Labs, with special thanks to Bill Bergman, Jim Van Duyne, and fabricator John Cade.
The installation was featured in WAITING ROOM: Immersive Art for Wellbeing at HOT•BED Gallery in Philadelphia. Curated by Lyn Godley and supported by The Jefferson Center of Immersive Arts for Health along with contributions from lightexture, Light Pebbles formed part of a research initiative exploring the relationship between light-based installations and individual wellbeing. The pebbles were also exhibited in the Troy Glow exhibition in New York, as well as in Un-Natural Mat(t)erials at the Center for Mediterranean Architecture in Crete.

Troy Glow - 2022
The following description is taken from the Arts Center of the Capital Region webpage which can be found here.
Troy Glow was a dazzling, temporary public art light festival in downtown Troy that ran nightly for five weeks, from December 4th, 2022 through January 9th, 2023.
Troy Glow features 6 beautiful outdoor installations of light-based art created by regional artists. In addition, 8 partner organizations created unique light displays, for a total of 14 Troy Glow sites in a walkable route through historic downtown Troy.
Troy Glow was created to give downtown Troy a “glow up” during the holiday season, which is also the time of year when there is the least amount of daylight. Visitors, shoppers, and diners were able to enjoy all the city of Troy has to offer while experiencing a unique, contemporary art light festival.
Waiting Room Exhibition - 2022
Waiting Room / Immersive Art for Wellbeing is an exhibition of dynamic light, shadow, and movement that creates immersive experiences designed to calm, inspire, or transform.
The exhibition featured work by six artists who use light, shadow, and movement to create experiences that mesmerize, enchant, and captivate. Each art installation was set up as a “waiting room” for the audience to spend time immersed in the experience, with the intention of calming, inspiring, and transforming. As part of ongoing research, viewers took part in a survey to collect feedback on their individual experiences of the various installations.
