Waterfall in the entrance is not a pre-recorded video but is the imagery rendered in real-time by a computer program, providing the ever-changing view just like the real waterfall. While this waterfall functions as a curtain, cascading to hide the rest of the area from the entrance, it gradually reacts and splits when the visitor comes close, allowing him/her to see inside. In other words, it allows the visitor to see only when he/she wishes. The entrance area changes as it reacts to the visitors’ movement and links to the surroundings only when needed. In this office, animals escort the visitors to the meeting rooms, giving an excitement before the meeting begins. Hallway functions as a wall when it is not being used, however, when it needs to escort the visitors to the meeting rooms, it shows a room sign and a “door knob” on a wall and becomes a door. By means of technology, we can get information only when necessary and keep the jungle-like environment otherwise.
