BART ads are still visible, though they are changed infrequently: a particular ad may remain up for several months before being replaced. The New York City Subway hosted two digital linear zoetropes through its Arts for Transit program. One, "Bryant Park in Motion", was installed in 2010 at the Bryant Park subway station, and was created by Spodek and students at New York University's Tisch School of Arts' Interactive Telecommunications Program. The other, "Union Square in Motion", was installed in 2011 by Spodek and students and alumni from Parsons the New School for Design's Art, Media, and Technology program in the Union Square station. Other places The Kyiv Metro (in Kyiv, Ukraine) also featured an advertisement about 2008 for Life mobile telephone carrier in one of its subway tunnels that featured the zoetrope effect. It was quickly taken down. In Mexico City, Mexico, an advertisement for the Honda Civic featuring a zoetrope effect was placed in one of the Line 2 tunnels. The Zurich Airport Skymetro features a linear zoetrope. 3D zoetropes 3D zoetropes apply the same principle to three-dimensional models, as already practiced by Czermak (1855) and Desvignes (1860) in predecessors of the zoetrope. In 1887, Étienne-Jules Marey used a large zoetrope to animate a series of plaster models based on his chronophotographs of birds in flight. Modern equivalents normally dispense with the slitted drum and instead use a rapidly flashing strobe light to illuminate the models, producing much clearer and sharper distortion-free results. The models are mounted on a rotating base and the light flashes on and off within an extremely small fraction of a second as each successive model passes the same spot. The stroboscopic effect makes each seem to be a single animated object. By allowing the rotation speed to be slightly out of synchronization with the strobe, the animated objects can be made to appear to also move slowly forwards or backwards, according to how much faster or slower each rotation is than the corresponding series of strobe flashes. Ghibli The Ghibli Museum in Tokyo, Japan hosts a 3D zoetrope featuring characters from the animated movie My Neighbour Totoro. The zoetrope is accompanied by an explanatory display, and is part of an exhibit explaining the principles of animation and historical devices. Toy Story Pixar created a 3D zoetrope inspired by Ghibli's for its touring exhibition, which first showed at the Museum of Modern Art in
