The Harry Potter phenomenon has reached such a saturation in pop culture that we’ve done our best to bring every aspect of it into our own reality. Now fans can visit the Leaky Cauldron, get lost in video games, host movie marathons or run around on broomsticks while battling for the Quidditch World Cup. But none of this will ever top what we’re able to create in our minds. J.K. Rowling’s books may be kid stuff to some, sure, but they are also the unmistakable cornerstones to this fanaticism. Through seven books, Rowling was our architect, and with each new Seuss-like magical gizmo, she challenged us to make them all appear in our minds. Millions of books have been sold and billions of imaginations have been lit up as a result.
