J. Meejin Yoon’s Light Drift was a three-night installation along the Schuylkill River banks (between Market & Chestnut Streets) that was up just for the weekend of Oct. 15-17, 2010. Yoon’s vacuum formed translucent shells were positioned throughout the area, both on land and water, and changed colors intermittently, though their “resting state” was a Mountain Dew-ish, alien green. But there was a logic to it all, you see:

"When a visitor approaches a land orb, the orb will start an “enticement mode” by pulsing between blue and green. If a visitor sits on the orb, the pulsing will transition to a blue state. The water orbs that align with the land orb will change colors at the same time, creating a linear extension of blue lights in the water."
