The Willis (formerly Sears) Tower, Chicago

How
do you make the observation deck of a 37-year-old skyscraper that hasn’t been
the world’s tallest since 1998 feel new again? You attach a series of
magnificently scary glass boxes, collectively known as the Ledge, to the
venerable Skydeck. The illusion that you’re standing unsupported 103 stories
above the ground is a real crowd-pleaser.

Observe This: The boxes are hung from a moving steel frame
that allows them to be retracted into the building to make way for the
window-washing rig. —Karrie Jacobs
