An artist took a Pringles can and used it as a pinhole camera — with incredibly amazing results, as he documents on his web site polaroids & pinholes. The images are weirdly haunting, like everyday objects seen through the eyes of an alien. The experience of using the camera is also aparently quite meditative, as the artist writes:

Total darkness as the colour paper is curled into the case of the tube.

Lid on, out into the light.

From half a minute to five minutes or more. A vague look at the watch, but more importantly, a calmness as the camera does its thing.

Back into the dark.

Always surprised at the results. Sometimes great patience is required to get a good result.
