Hi all, I have just ran across a nearly endless supply of cardboard tubes, that would make great pinhole cameras. They are 16" tall, 5.5" wide, and 18" around. I have posted a couple of photos at http://www.james.kellar.com/tube1.jpg and http://www.james.kellar.com/tube2.jpg. If you want one get in touch with me and I'll see about the cost of postage.
