This one's really great :) Do you have a picture of your camera? I've once made a panoramic pinhole (sort of; it had two pinholes --> twinhole) of an oversized matchbox. It was fun but the images aren't as sharp as yours. Well, the hole was way too big I guess.
I'll post one soon on my blog www.lofiphotog.wordpress.com.
I actually went about fashioning the pinhole in a very scientific manner, again I'll elaborate more in the blog. Not enough time or room right now. Thanks for looking!
Thanks, I'll stay tuned :)
