Harry Potter's brand of magic may not exist in the real world, but smartphone applications, electrical engineering and plastic wands sure do. Maguss uses all of these things, plus a badge that acts as a motion-sensing receiver, to bring wizard duels to the physical world. Maguss is on Kickstarter right now, seeking $66,191 to create and ship a kit allowing wannabe wizards to challenge friends to duels in-person and online. Players cast spells by waving the wand in specific motions -- in-person, the motion is picked up by the enemy's badge and smartphone app. Online, players conduct spells at their own badge and the motions are transferred to the rival wizard's app. In either scenario, whoever has the best wandwork wins.
