The initial sketch-like animation of the office setting.

The video opens with a black and white sketch-like animation of an office environment. Three people are shown working at desks. A man in a suit is reviewing documents at his desk, a woman is typing on a laptop at her desk, and another person is working at a computer behind a partition. The scene transitions to a man and two women standing in front of a whiteboard with diagrams and text. They are interacting with the whiteboard, with the man and one woman pointing and writing on it. The video then transitions to a full-screen graphic with the text 'WhiteWalls' and 'Bring your office to life!'.
