Google’s May 30, 2012, doodle showcased interactivity at its most decadent. To commemorate jeweler Peter Carl Fabergé’s 166th birthday, Google encased each letter of its logo in a unique Fabergé egg that would open with the click of a mouse. The artist was a favorite of the Russian royal family’s, designing intricate versions of his signature eggs annually, each more elaborate than the next. His reputation as a meticulous designer earned him a spot as Russia’s representative in the 1900 World’s Fair in Paris. As tribute, Google’s doodler went through many incarnations of the design before settling on the final, artful one.
