@NinaHilliard we've made this one and it's super easy! We have a giant white wall we watch movies on with this projector!!! It works great outdoors too!! We stream our movies from our computer to our phone through VLC.
The Projector Ring - There’s a transparent slide installed and a lens on the opposite side. When you send a ray of light through it the ring makes a decent projector. The built-in slides can be changed at will. Awesome!
