Ideogram was a stainless steel sculpture in New York City by American sculptor James Rosati, completed in 1972.

The work consisted of a number of intersecting beams with reflective surfaces.

Located on the Austin J. Tobin Plaza,[2] in front of the Marriott World Trade Center, the work was lost in the September 11 attacks.

Though the sculpture may have survived the attacks and collapse of the buildings, its steel material was indistinguishable from the Ground Zero rubble.

As a result, the sculpture was never recovered, and its remains were removed from Ground Zero along with the rest of the rubble.
