POV technology, otherwise known as persistence of vision technology, exploits the eyes penchant for completing images even without all the necessary information. Movies were built on that principle, having allowed generations of people to experience a new form of entertainment that is still dominant today.
The Trickstick by Electricks takes the idea of POV and applies it to an unassuming wand. Wave it quickly enough, though, and 128 LEDs work together to produce 60fps images that can be uploaded to it with the use of a companion iOS/Android app.
