Amazing pinhole camera

 The technicians made me some fabulous pinhole cameras. You can see the view of the trees in the distance in the first picture. It was better is real life because putting my camera to the hole let in too much light from the back.

The design is based on a Pringles tube but the screen is most of the way down the tube and the rest of the distance from the eye hole to the screen is just to keep the screen dark enough to see the view. Wonderful!
