Kati had to work from the age of 14, because the low wage her mother received for being a cleaning lady in the local catholic high school wasn't enough to sustain themselves.

[12][13][14] The final form of art she learned was glass painting (including icons) - her first major work in this field was the decoration of the cabinets at her own exhibition.

She decided to involve herself in this art after she got to enjoy the motives (including flowers) and colors of wall painting.

[32] The motifs, images and signals depicted on the egg commemorate different important moments and symbols of Hungarian history,[30][33] including the Hungarian crown jewels, the turul, the Conquest of the Carpathian Basin, the Blood oath, or the Treaty of Trianon,[6][34] as well as the Assumption of Mary and 16 golden horseshoes.

[23] For easier understanding, Zsigóné also made a 30-page illustrated guidebook, which includes explanations of the symbols found on the egg.

[40] Created on an ostrich egg using two different decoration methods, painting and engraving, depicting 100 different patterns, which are placed in an elliptic shape, representing the rotation of the Earth.

[47] The egg depicts 40 notable historical figures, including Albert Einstein, Thomas Alva Edison, Marie Curie, Ignác Semmelweis, Ede Teller, Isaac Newton, Stephen Hawking, Leonardo da Vinci, Nikola Tesla, Wolfgang Amadeus Mozart, Mahatma Gandhi, Mother Teresa, Yuri Gagarin, Jesus Christ, and Pelé,[48][49] among others, as well as 4 contemporary figures like Bill Gates and Oprah Winfrey.

[52] Furthermore, the egg depicts 14 well-known buildings and structures like the Giza pyramid complex, the Great Wall of China, the Christ the Redeemer statue of Rio, Taj Mahal, the Moai statues, or Petra of Jordan,[53][50] as well as 30 objects and expressions which bear importance in the human life, like peace, the DNA, time, writing, family, numbers, movie, flight, healing, time etc.

[55] The artist spent no less than 3 years decorating the egg, the craftsmanship itself took 6 months, the rest was collection and processing of the materials.
