The Markus Raetz 'Yes -- No' piece is one of the moodiest structures to date. Ask it a simple yes or no question and it will provide you with both answers as you walk from one side of the piece to the other.
This sculpture houses an extremely innovative design so that it changes its appearance depending on the angle it is being viewed from. By choosing the words "yes" and "no" as his main subjects, Markus Raetz has formed a piece of art that covers both ends of the deciding spectrum. It goes to show that a picture (or sculpture) can actually speak a thousand words. If you are looking for a definitive answer from this design, you may want to look elsewhere.
