So what are we looking at in this picture? This is Harry Potter after the Epilogue of the last book. As you can see, Harry has found a steady job and has long since given up a life of adventure so he can afford to send his kids to Hogwarts. His couch potato boring life makes him long for Voldemort to be resurrected yet again.
Just kidding. This is the Kymera wand, which allows the user to wave up and down to change the channels. A clockwise or counter-clockwise motion changes the volume. It is available for pre-order at this site in October for about $84.
