Yes/No typographical sculpture by Markus Raetz

As you walk around this model the meaning and text changes from yes to no.  I have always loved sculpture and illusion and so when I found this sculptuer by Markus Raetz, I had to recreate it. The sculpture is called "Yes/No typographical Sculpture"  and the original can be seen in the photos above.  This model is made from 4 parts and is slotted together using pins.
