New attraction in the Windy City - the Tilt!

Saw a news story about the latest attraction in Chicago at the John Hancock building - It's the Chicago Tilt. Up to eight people can fit inside the glass and steel moveable platform that slowly tilts outward on an angle, providing downward-facing views of the city from over 1,000 feet above.  Heights don't really bother me, so I think I would do it, but I know plenty of people who would be in a panic if they even thought about trying it.
