Facebook doesn’t need a remembrall when it comes to celebrating the 20th anniversary of Harry Potter.
The social media platform got into the spirit of things on Monday — which marks the day Harry Potter and the Philosopher’s Stone (or Sorcerer’s Stone for U.S. readers) — by hiding a few Easter eggs for users of its mobile app.
When users post or comment using a name of one of the four Hogwarts houses (Gryffindor, Ravenclaw, Slytherin, and Hufflepuff), the text takes on the color of the house. This also happens when a character is mentioned from the series (like Harry Potter or Draco Malfoy), with their names taking on the colors of their respective houses. (Wonder how many social media house points that is worth?)
And for its last trick, Facebook has made it so if users click on one of the newly colored words, a wand appears and casts a little spell. (Catch a glimpse below.)
But the social media giant isn’t the only one adding some fun anniversary related features. Twitter introduced a special emoji of Harry’s iconic, round-framed glasses with an accompanying red lightning bolt-shaped scar that appears when fans tweet using the hashtag #HarryPotter20. It also introduced some fun facts about what people tend to tweet about when it comes to the franchise around the boy wizard.
Since Harry Potter and the Philosopher’s Stone debuted in 1997, the book and its six ensuing sequels have gone on to spark an entire universe of films (including the Fantastic Beasts movies) and a two-part play.
