A wall projection project from architectural firm NBBJ shows a range of pictures that represent who you are as you walk by.
The idea behind fluidWall is to use digital content as architectural material, which in turn will create a conversation. This lets people learn more about you than they would typically be able to gleam from a once over glance. If you see something that interests you as well, it gives you the opportunity to start talking to each other.
The user curates the images, so they still retain a measure of privacy despite the feature that anyone who walks past can activate the wall projection. NBBJ foresees the fluidWall being used in offices, where each employee is outfitted with a RFID card that activates the pictures.
