Yeah with a pinhole camera, I just don't know how to make one with a small enough aperture/low enough ISO film.

I wonder what ND- you'd need with ISO100 film and a pinhole...

Public service for all illiteratefags, quoting from the site linked in OP:

Solargraphs are easy to take. All you need is an empty drinks can, some photographic paper and lots of gaffer tape. Put the photographic paper into a drink can camera, cover the lid to keep out the elements, find a position pointing towards the Sun, and fix the camera well. At the end of the exposure period, place shutter tape onto the hole. Find a dark room with a computer. Scan in a 5x7" piece of blank paper (so the scanner knows the area to scan). Now, without developing it, scan the photo paper on a high resolution. Save the negative image on your computer. You'll need to invert and flip the image horizontally. For more information, see Justin Quinnell's website, www.pinholephotography.org.

I remember reading articles about this kind of shots in normal, non-photography related magazines. I even remember one article had detailed instructions on how to make the camera from a pringles can. So I always thought the "how to" part was common knowledge.
