It’s not as crazy an idea as it seems at first. If you’ve seen the “camera” on the iPad 2, you’ll know how small it is: basically a pin prick hole. The aperture on compact digicams are so small anyways they might as well be called a pinhole, except thay have a lens in front and a pinhole camera does not.
So, if you have never experienced a pinhole camera, this video shows you how to make one using a spare body cap on your DSLR. The blurry (dreamy?) effect could be creatively used in some video shots. I wonder if you can make use of digital zoom? And what if I use an extension tube. Someone (lensbaby?) should make these pinhole body caps.
