This backpack is a walking digital billboard. 📲👀 Persona is doing something interesting by putting their customizable LCD screen right behind a clear, transparent front backpack window. You control what is shown on the display via a mobile app, which runs off a portable power bank tucked into a secure inside pocket. It can flash video, pixel art, custom text, or any animation you want. 🎥 #TechGear #Backpack #CoolTech #Tech #Gadget
