A massive banner unfurling down a skyscraper.

A time-lapse video shows a large banner being unfurled down the side of a tall, modern office building. The banner displays a series of line drawings depicting hands interacting with colorful shapes, resembling origami or paper folding. As the banner descends, the sky changes from cloudy to clear blue, indicating the passage of time. The surrounding cityscape is visible, with other buildings and a street with traffic below. The video ends with the banner fully displayed against the blue sky.
