Mr. Beam is a company that uses the sides of large buildings as the canvas for light shows (an idea pioneered by the hackers of the Chaos Computer Club, and now adopted by a large number of department stores around Christmas time).
Their Living Room concept does the same for a room filled with white furniture. As Oh Gizmo says:
Using only 2 projectors and some extremely careful planning and mapping, they’re able to project an entire 360° decor onto a living room filled with white furniture. This includes projected wallpaper and even carpeting. The concept, which is not unlike Michel Gondry’s Dead Leaves And The Dirty Ground video for The White Stripes (RIP), could make it really easy for interior decorators to try out an infinite number of pattern and color combinations before committing to a new decor in a room. That is if Mr. Beam ever decides to commercialize it.

As of today, the Royal Palace in Amsterdam will be open to the public again. The former 17th century city hall had been closed for renovations for three years.
