I have added this photo to the left specifically to show how one could view the display from behind and still see through to the display on the other side of the isle.
These are exceptional photos taken by a talented photographer with no special lighting or arrangements for such an endeavor... as photographing an exhibit behind glass, with patrons walking about the display continually is no doubt a challenge!
This photo also show closeup the unit pieces.
If folded correctly, once assembled the origami "holds itself together"! There is no glue or tape involved here!
You can also see the wonderful array of papers available for the origamist to fold.
Many of these are available for order from suppliers online!
In the red, kusudama ball to the right of the cranes, I used a mylar wrapping paper for some of the pieces. It produced a wonderful effect when the ball was finished.
The hanging strings of cranes were from the linen papers (red) and lovely pastel origami papers.
