The Pictureland projector was made in the shape of a slumbering Big Bird, sleeping in a cozy bed and holding on to his teddy bear, Radar. When the projector is switched on, it plays "Brahms' Lullaby" for six minutes, and projects illustrated images from a transparent disc onto the ceiling. There are three interchangeable discs, each with a different theme. One disc has Sesame characters posing with letters of the alphabet and objects that begin with that letter -- Big Bird has birds and bugs, Ernie has an elephant and an egg, and Grover has a goat.
