With a certain amount of acrobatic skill, a nimble player can explore the roof of the building, with several loudspeakers connected via a series of tightropes. Hitting the loudspeakers will result in a message warning against vandalism.
Crystal and Clem apparently gather on the roof to talk about "the project", a plan of theirs which may have involved committing suicide together. After completing Levitation, Chloe can be seen on the roof trying to extend the antenna's reach in order to send a message across space.
At night, Elka and Nils are standing where Kitty and Franke were at during the day holding hands and looking at the sky.
Quentin Hedgemouse and Phoebe Love can always be found here, practicing with their band. Phoebe plays drums, while Quentin accompanies her with turntables, occasionally also providing vocals.
After the vision of Loboto in the Brain Tumbler Experiment, Dogen can be found here brainlessly watching television. Later still, Kitty and Franke are also sitting here debrained, accompanied by a perfectly healthy Vernon keeping them entertained with a story about the Civil War.
