In the video, a man is standing on a stage in front of a blue background. He is wearing a black t-shirt and is speaking to the audience. He is using hand gestures to emphasize his points. The video is shot in a vertical format, and there is a subtitle at the bottom of the screen that reads, \"So when light shines on the phone, the arrows will flow giving the sense of speed and acceleration.\" The man appears to be explaining a concept related to the movement of light and how it can create an illusion of speed and acceleration.
