Right in the middle of Millennium Park in the heart of downtown Chicago is the awesome shiny gift from the Aliens. (Grey or Green aliens? Not sure) When you stand under it and look up you can see your reflection in about 30 or 40 different spots due to the shape. It's perfect for most of the people who Facebook everyday. They can stand there and look at themselves all day. They can even Tweet to their other selves while they're there.
That aside - the chrome bean is an awesome sight.
