We have developed a mouse for interaction with 3D graphics based on a
computer vision technique.  There are several LEDs on the mouse moved 
around by the user, and a camera faces the user and detects the patterns 
of LEDs images. We compute the position and orientation of the mouse 
from these images in real time. I am preparing a slide presentation about 
this technique, and I would like to show a photograph of Picasso for which 
he moved flash lights in front of the camera that had its shutter open, so 
the lights draw nice arabesques on the picture. He is drawing with light
and we also draw with light with our mouse (We can also sculpt).

I have seen this Picasso picture on a SIGGRAPH video. 

I went through many shelves of Picasso books in libraries without success.  

Has anyone seen this picture in a book about Picasso?  

Many thanks for your help.
