"Pin holes" can be using found from boards, fingers, Venetian blinds, trees, etc. The further away, the bigger the image.

Pro: Size of image can be much better than with shoe box camera because distance is further. Compare images from different hole sizes. Multiple holes make fun effects.

Con: You might forget to look and find them!

View partial eclipse with pin hole camera made from shoe box

A pin hole camera made from shoe box is frequently recommended as a safe way to view a partial eclipse.

Pro: Probably couldn’t hurt you if you ate it. Can get images of surrounding wispy clouds.
Con: Image is very tiny.  Awkward to photograph. Thrown in a corner and ignored, so no photo.

But if you think bigger, much bigger, the concept can be pretty fun. See a following blog entry on found objects.
