@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.
Now you can have the luxury of a big screen movie in the palm of your hand! With a portable HD projector for your iPhone you can use your phone to project movies on screens up to 60 inches! The sky is limit; just plug and play your movies on any blank wall. Hang a bed sheet outside and turn your backyard into a theater this summer, making memories for your kids that will last a lifetime!
