This 47 floor building in downtown Miami was built for the CenTrust Savings & Loan in 1987. The skyscraper has had several names since. In 2010, it was renamed the Miami Tower. The unique, three-tier design has a $1.5 million LED lighting system. This allows the exterior to be bathed in different color schemes. For another optical treat, try staring at the horizontal lines in this photo. After a while, they can create dizziness that borders on vertigo.
