probably none will be as impressive as the ones created by this man. Slovenian artist Franc Grom uses simple tools to create this - an intricate and stunning artwork achieved by drilling thousands of tiny holes into an egg shell. SOUNDBITE: Artist, Franc Grom, saying (Slovenian) "When I start working on an egg, I don't know exactly how it would look like in the end. I create the design along the way. I do a basic lace-like pattern, and then I fill it in. Sometimes it turns out beautiful." And beautiful they are - though Grom says mimicking traditional Slovenian lace patterns takes a lot of patience and precision. SOUNDBITE: Artist, Franc Grom, saying (Slovenian) "The most difficult part is taking care that the holes are drilled close to each other without breaking the shell. I have set my personal record some 3-4 years ago, with a little over 24,000 holes drilled into a single goose egg." Color is achieved purely by careful polishing. While Grom keeps a large collection of his favorite creations at home he does sell them as souvenirs and for special occasions. But eggs-quisite artwork doens't come cheap, interested buyers have to pay about 100 euros per 1,000 holes.
