As much as I think I’m tech savvy, something new and exciting is always coming out! This window film by Sonte can be applied to your windows and go from transparent to opaque in a second thanks to your smart phone. How crazy is that?! This product is perfect for almost any room, and can even be used as a backdrop for a TV projector. For about about a ten square foot section it will cost you about $284 for the film with the smart phone activated strip. Check out their video here on how easy it is to install.
