In August 2004, a photo shoot was completed in Buffalo of about 1,800 nudes in Buffalo's old central train station.
On April 15, 2007, Tunick organized an installation in a tulip field in Schermerhorn.
On August 18, 2007, Tunick used 600 nude people in a "living sculpture" on the Aletsch Glacier in an installation intended to draw attention to global warming and the shrinking of the world's glaciers in a collaboration with Greenpeace. The environment-oriented installation was reported in several languages and media outlets around the world, Swiss politicians were playfully encouraged to demonstrate their green credentials by participating in Tunick's installation, and Euro RSCG Zurich, Switzerland received the AME Grand Trophy for Public Service and Not-For-Profit, for their campaign for Tunick and Greenpeace Switzerland, "Naked Testimony to Global Warming".
On June 17, 2008 Tunick carried out an installation in the grounds of Blarney Castle in County Cork with about 1200 people.
In his work, he plays off different flesh tones or groups people of the same color.
On June 26, 2004 in Cleveland, he completed his largest installation in the United States, with 2,754 people posing.
On October 3, 2009 Tunick performed another installation in collaboration with Greenpeace, this time to draw attention to the effect climate change is having on French wine production.
Tunick cites 1994, when he posed and photographed 28 nude people in front of the United Nations building in midtown Manhattan, as a turning point in his career; "It all started there, moving my work from just photography into installation and performance photography," he says.
Tunick's philosophy is that "individuals en masse, without their clothing, grouped together, metamorphose into a new shape.
Over 700 volunteers turned up at a vineyard near Macon, France for a number of poses among the vines. The press were allowed a photoshoot at Peel Park, Salford on May 1, but the other locations such as Castlefields, Dantzic Street and Ringway remained unreported.
On March 1, 2010 Tunick carried out a series of installations titled "The Base" on the Sydney Opera House Forecourt and inside the Opera House. On August 8, 2010, around 700 revellers at the Big Chill Festival, at Eastnor Castle Deer Park in Herefordshire UK, shed their clothes and covered themselves in five shades of body paint for an installation that paid homage to the art of Yves Klein, Mark Rothko and Ellsworth Kelly, and made reference to the BP oil spillage in the Gulf of Mexico.
