The image shows a man standing in front of a whiteboard in a classroom. He is wearing a black hoodie and glasses and is holding a piece of paper in his hand. On the whiteboard, there is a diagram that appears to be a flowchart or flowchart. The flowchart is written in black marker and is divided into three sections. The first section is labeled "Outsiders", the second section is titled "Inside", and the third section is labelled "Pump". There is also a label on the right side of the board that reads "Idea". The man seems to be explaining the flowchart to the viewer.
