Pyramid Reflections
After three different pictures of the façade of the Transamerican Pyramid today, three different pictures with reflections of the Transamerican Pyramid.
For all pictures I used the reflecting property and distorting qualities of cars in the direct neighbourhood of the building.

Facts
■The Transamerica Pyramid is one of the most recognized buildings in the United States.
■Tallest building in San Francisco for 45 years; surpassed by Salesforce Tower in 2017.
■Throughout its construction, the boarding surrounding the emerging site boldly boasted: A San Francisco landmark since 1972.
■ The foundation consists of a steel and concrete block that sits 52 feet underground and is designed to move during earthquakes.
■ Components of the base include approximately 16,000 cubic yards of concrete, encasing more than 300 miles of steel reinforcement rods.
■ The top floor (48th) features a tenants-only conference room with 360-degree views of the city and bay.
■ Only two elevators reach the top floor.
■ The 'spire' is the upper 212 feet (64.6 meters), and is covered with vertically louvered aluminum panels. The lower portion of the spire encloses mechanical equipment.
■ A virtual observation deck has four cameras at the very top of the spire pointed in all directions. In the lobby there are four monitors broadcasting the images 24 hours a day.
■ During the 7.1-magnitude Bay Area earthquake in 1989, the top story swayed nearly a foot from side to side.
■ With 3,678 windows it takes a month to wash them. (source: https://www.emporis.com/buildings/118715/transamerica-pyramid-san-francisco-ca-usa)
