You can use a pinhole as a projector as long as there is a big enough difference between the light levels. In the Victorian days people had camera obscura buildings out in their gardens. You go into these dark little rooms when the outside was very bright and through the pinhole the bright outside is projected onto the back wall. Upside down of course.

At my studio I have a bathroom with an old style keyhole and there is a window perfectly situated opposite the door with a blank white wall in the hall. If the sun is streaming in at the right angle I can see a perfect image of the window projected on the wall, complete with the texture in the curtain and all the objects on the sill.
