Slovenian artist Franc Grom, aged 72, makes unbelievably intricate egg sculptures using just a tiny electric drill and enormous patience. According to National Geographic[1], when finished, each egg contains approximately 2,500 to 3,500 holes. While Slovene artisans usually paint their eggs using a technique called drsanka[2] by lightly scratching intricate patterns into the surfaces of colored eggs, carving them was solely Grom's idea.
