A mobile phone displays a video with special effects. The video is filmed from above a tile floor with white and gray tiles in a geometric pattern. A dark gray box sits in the center of the frame, balanced on its corner. Above the box, a robotic arm descends into the frame and shines a red light on the box. The phone is held by a hand; the video is displayed in portrait mode, and the top and right edges of the screen show typical social media buttons.
