Window Screen

We have an interior window in our bedroom that gives onto the stairwell.  We put it there so that the light from the stairwell goes into our bedroom.   In order to have some privacy, we decided to frost it.   We did it with a "spray".  I always found that it did not do an even job.   It bothered me.  Laser-Cutting to the rescue!  I decided to add some decoration to it.  

The window is about 25" x 108".  I wanted a screen that looked like this:

I designed it in SketchUp, and divided it into 30 or so pieces to cut.   The screen is two 1/8" layers stacked on top of each other.   The divisions are made at different places in each layer, so that when they are glued to each other, they form one large screen.

Once cut and put in place, it looked like the following.   It looks especially good when there is light shining on the other side.
