The newly opened Burj Khalifa is a stunning 2,717 feet tall. To put that in perspective it's almost like stacking two John Hancock Centers on each other. Chicago's John Hancock Center, 9th tallest building in the world, is 1,127 feet tall.
Three years ago, I blogged about what a double Hancock would look like. Little did I know there would be a building almost that tall in 2010. Wild.
I would also just like to say that I am very happy that you don't host your pictures on Flickr! Work blocks many sites, including Flickr and I cannot see a lot of the pictures on friends' sites that I visit because they are linked to Flickr.
