Genesis Poi: DotStar LED Persistence-of-Vision
High tech, all-season, water- and playa-resistant poi that you can build and customize yourself!
by Phillip Burgess
Persistence of vision (POV) is the illusion of a solid image where there is none — a task for which LEDs and microcontrollers are a natural fit. Poi is a performance art of spinning tethered weights. Some of the most dramatic performances use fire poi! We sought to create something with that level of “wow,” but safer and usable indoors or out. And so these “Genesis” POV-poi were born.
