Giant Clock

I read a couple of days ago about how the world's largest clock has been installed as part of a new super tall building being built in Mecca, Saudi Arabia. The building itslef reminds me of the Soviet era Seven Sisters buildings in Moscow. Getting back to the clock, it has 46 meter faces, that is like 150 feet across (WOW, that is big). Here are a couple of links about the clock and the tower:
This bottom image is how the building is to look when complete. The building will be nearly 2000 feet tall when complete.
The first link in the post has the best photos but each of them has different pictures and are fun to check out.
