In the video, a person is holding a smartphone in their hand and swiping their finger across the screen. The screen displays a colorful pattern that changes colors as the finger moves. The colors transition from purple to blue to green, and the pattern appears to be a radial burst of lines emanating from the center of the screen. The person's finger moves smoothly across the screen, causing the colors to change and the pattern to shift. The video is shot in close-up, focusing on the interaction between the finger and the screen.
