Not entirely zen-related, but sort of. Today, I got an enso I bought from Kaz Tanahashi. It's on my wall, above where I sit. It won't stay there, though, because, well, if my eyes are open, it will distract me.
It's a beautiful piece of artwork. It's 30 x 36 inches, which is about the size of my zabuton; in other words, it's huge.
This photo does not do it justice...
