I'm excited about this new pinhole camera. I've never purchased a commercially made pinhole, other than a recently acquired Holga, but this one I would consider.

Simon, one feature I'd like to see included are viewing lines or dots on the sides and top of the camera, as an aid to composition. I have this on many of my homemade box cameras and it's a wonderfully simply and surprisingly accurate method of composing on a camera otherwise absent a viewfinder.
