When walking through the east end of the infinite corridor, passers-by may occasionally be treated to the whimsical tinkling of ancient bells. These sounds emanate from speakers installed as part of a exhibit on early metallurgy practices in ancient western Mexico. The display is based on a book called The Sounds and Colors of Power
written by MIT Associate Professor of Archeology and Ancient Technology Dorothy Hosler. Pushing the button to the right of the board after business hours (workers in nearby infinite corridor-offices are apparently not amused by the continual ringing) causes the recorded bells to play their short serenade.
