In digital media, the term “Easter egg” refers to fun, hidden references for users to uncover — not entirely unlike the pastel-colored eggs the Easter bunny hides every spring — ranging from phrases to images and everything in between.
Think of these Easter eggs as rewards from creators for anyone who takes the time to dig into a product long enough to see what’s there. Alternatively, they’re a pleasant surprise to a user who happens to stumble upon them.
They’re gratifying to seek out because, typically, no one knows in advance that they’re going to pop up.
Probably the most familiar example of an Easter egg appears periodically on the Google homepage. Often, these will be whimsical animations that appear (and are relevant to) a specific day of the year. This is a kind of Google Easter egg that most people have experienced.
