This is a place to come to look at all your vacation memories. On a long wall in a hallway, artfully arrange framed photos with other objects collected on family vacations. Notice all the photos are framed the same to help unify the various images.
This is a solution for a long straight wall with no architectural details. No sense in trying to hide large TV's anymore, they are what they are, and we all have them. Just surround them with beautiful objects so it isn't the focal point.
