This photo quality is not good, but you can just see the real effect is up on the ceiling above.

Simple and beautiful.
In this respect it was enlightening to visit "SLASH : Paper under the knife" in NYC last year. To see all the work being made of paper - a lot of it cut paper - highlighted the multiple approaches possible within the same medium.

There was some beautiful work in the Paper exhibition, but to me the pieces with a strong conceptual approach really shone. I'm including this image as it is similar to one she had in that show.
