Co-blogger Candace Keener has written much of late about sheep, as well as a potential affinity for shepherding. Well, shepherding may have just become even more appealing with its debut into the arenas of both environmental and performance art.

Today, Inhabitat ran a post on Baaa-Studs, a Welsh group that blanketed the backs of hundreds of sheep in LED lights and coordinated their movements. Judging from the group’s video, they used sheepdogs to herd the flock into formation and remote controls to manage the light displays (as well as plenty of editing and perhaps some digital alterations).

While shepherding itself sounds awfully green and pastoral, the introduction of energy-efficient lights throws it into a decidedly environmental realm. LED lights use considerably less energy than traditional bulbs. They also emit very little heat — good when you’re coating the backs of already wooly sheep.
