Measure time, see the Earth turn

Visit the architectural wonder that is Leon the Pendulum (named after the French physicist Jean Bernard Léon Foucault). Installed in 1983 and located in the lobby of DEV, the Development Office Building (2901 N. I-35), the pendulum remains a well-visited attraction which won the Austin Chronicle 2007 award for Best Moment of Zen That's Not on 'The Daily Show.' Spanning four stories, Leon appears to rotate once every 48 hours, although it actually swings back and forth in the same place while the Earth turns beneath it.
