The Camera Obscurer

I thought Abelardos' work was really beautiful. To see his images of life, outside, projected onto still life's, inside, was fascinating. The images were very engaging, they created a story,almost, inviting you to read. The idea that the images outside are moving and represent a different viewpoint of life to that of the images inside the room creates a story board of sorts.
I have never seen a Camera Obscurer before and found it very interesting. I particularly liked the one with the still life. When the objects were moved it made me think of simple animation.
I would like to view the other one another time when the light outside may give more definition to the view.
I had read about art masters of old that may have used such cameras to help them with their paintings and now I can see how these could have been beneficial to them and helped with their mastery of light and perspective.
