The video shows a man standing on a stage with a red circle and the words "TEDxLeuven" in the background. He is wearing a blue shirt and black pants. The man is holding a small, round, red object in his hand and appears to be speaking to an audience. He moves his hands and body in a way that suggests he is explaining or demonstrating something. The stage is lit with blue lights, and there is a black curtain in the background. The man's shadow is visible on the stage floor.
