Wenda Gu's Tunnel of Hair.

Avant-garde artist Wenda Gu displays his "tunnel of hair" artwork, made from 430 pounds of human hair, in Dartmouth College’s library – just in time for commencement ceremonies!

Dartmouth’s Baker Library is hosting a multicolored braid of hair more than 7 miles long, looped from floor to ceiling. The work creates the impression of a "tunnel of hair," says Brian Kennedy, director of the Hood Museum of Art at Dartmouth College. The braid is divided into pieces and reconnected with tags bearing the names of every country on Earth — written backward. It’s a reference to how the world has become more divided than united over the years, Gu says. The hair came from wig factories in India and Shanghai.
