The AirAura is plug and play! Take it out of the box, put it on any surface you want, turn it on and it will immediately show some hologram displays that come built in!
Then, you can download the AirAura app on iOS/Android and add any images/videos you want and it will project them directly on the AirAura!
(If you don't want to download an app, you can also connect a USB drive with pictures/videos)
