In this image the Pyramids of Giza, on the outskirts of Cairo, are transformed into almost two-dimensional shapes. The Great Pyramid – the largest structure at the site – is the oldest of the seven wonders of the ancient world and the only one to remain largely intact. With an estimated 2,300,000 stone blocks weighing from 2 to 30 tonnes each, the 481ft pyramid was the tallest structure in the world for more than 3,800 years.
