Shepard, but since 1991 has been the home of Blue Man Group, which now owns the theatre. The Joseph Papp Public Theater (home to the New York Shakespeare Festival) is located across the street in the former Astor Library building. The trapezium-shaped traffic island in the center of Astor Place is a popular meeting place and center of much skateboarding activity. The island is most notably home to Tony Rosenthal's sculpture "Alamo", known popularly as "The Cube", which consists of a large, black metal cube mounted on one corner. Installed in 1967 as part of the "Sculpture and the Environment" organized by the New York City Department of Cultural Affairs, the Alamo Cube has since become a popular meeting place in the East Village. The sculpture can be spun on its vertical axis by one person with some effort, and two or more people without trouble. In 2003, the cube was the subject of a prank played by the ATF squad (All Too Flat) in which it was turned into a giant Rubik's Cube. The members of the organization were careful with the prank, as they didn't want to be destructive. The cube stayed up for about 24 hours before city maintenance removed the painted cardboard panels from the sculpture. On March 10, 2005, the Parks Department removed the Cube for maintenance. The original artist and crew replaced a missing bolt, and made a few other minor repairs. A makeshift replica of PVC tubes named the Jello Cube in honor of Peter Cooper was placed in its stead. As of November 2005, the Cube returned with a fresh coat of black paint, still able to spin. Other nearby points of interest include: In 1860, Abraham Lincoln came to the attention of the fledgling Republican party with his Cooper Union Address. Given in The Cooper Union's Great Hall, the 'Right Makes Might' speech examined federal control of slavery and the thoughts of the signers of the Constitution. Cooper Union also housed one of the first free public libraries. One of the original libraries making up the New York Public Library, the Astor Library was housed in the Astor Library Building. The building is home today to Joseph Papp Public Theater. The Astor Place subway station () is among the original 28 subway stations, and is on the List of Registered Historic Places in New York.
