A recent patent filed by Google could make decorating for the seasons much easier.  The tech company has outlined plans for a projection system that uses a combination of lasers and  photo-reactive paint to create unique digital displays on a user’s walls.  The technology may even be capable of supporting video feed, allowing people to turn their walls into TV screens. 

Similar to a computer wallpaper or screensaver, a person could easily select and change images in a variety of themes, like “Halloween” or “Sports” using a smartphone or remote control.  With the simple touch of a button, what looks like regular paint could easily be transformed into a floor-to-ceiling screen. 

Students at the Royal College of Art in London were also experimenting with walls when they created a conductive paint that eliminates the need for wire cables and sockets.  “Bare Paint” works as a form of liquid wiring, and can be applied to the wall to create working light switches, circuits and more. It’s a non-toxic, water-based substance that dries quickly to become electrically conductive, perfect for a number of different DIY purposes.  The patent, originally filed by Bare Conductive Ltd. in 2010, even covers applications for the ink on the human body, and “enables such a body to function as part of an electrical circuit.” 

The Penn State Research Foundation also got creative with its patent in 2009 for a “Transparent sustainable wall system.”  Comprised of double pane insulated glass and lined with photovoltaic cells, the structure provides maximum natural light while generating solar electricity.  The technology, known as Building Integrated Photovoltaics, allows for more easily modifiable building structures and uses recyclable materials to provide a greener form of energy.  Ideal for residential construction, the panels also come prefabricated for easy installation.
