An image I’ve selected is the flow visualization around sleigh of Santa. This video screenshot vividly depicts the drag forces generated by the sleigh moving through a fluid.

This is an excellent example that shows the perfect balance of aesthetic and interesting scenery and fluid science. We can see how viscous drag is forming as a result of friction between the fluid and sleigh. Also, pressure drag forming from the sleigh shape.
