Like so many of my classmates, I probably had an M.C. Escher poster on my dorm room wall at some point during high school or college. I certainly grew up with at least two jigsaw puzzles made from his artwork. An inventor in England was inspired, and created a wonderful illusion, where water flows uphill. Most amusing part of the article for me was the description of the man responsible: “Inventor James Dyson, he of the bagless vacuum cleaner” I guess everyone hopes to known, for whatever reason. Not having seen or used a bagless vacuum cleaner, I won’t comment on how ingenious the fellow might or might not be, but certainly the BBC found it noteworthy. Anyway, there are pictures, diagrams, and explanations of how the illusion of water flowing uphill was created.
