This one is called "Jurisprudents," made with over 3,000 small head sculptures:
Using traditional methods, the artists sculpted twelve life-size portraits of ordinary American citizens-representing twelve members of a jury. The heads were then laser-scanned, rapid-prototyped at small scale, cast in pewter in large quantities, finished with a hand-rubbed patina, and precisely affixed to hundreds of suspended cables.
Collectively, the over 3,000 small sculptures coalesce into two monumental heads facing each other across a skylit courthouse atrium. In creating an abstract representation of implied dialogue, this artwork honors a legal system rooted in the voice of the people.
