The sun appears in many positions in the sky... http://en.wikipedia.org/wiki/Sun_path
a snapshot of them over a year, at the same time of day, reveals the analemma http://en.wikipedia.org/wiki/Analemma http://www.analemma.de/english/analem.html
but what if you snapshotted different points in the sunpath over the year? You could write a word. (and it should only take six months maximum! ;) The effect would be that of a dot-matrix font.
So, what should such a celestial dotmatrix "printer" write as it's first message?
"hello, world", of course! http://en.wikipedia.org/wiki/Hello_world_program
(in fact, you'd only need 7 days (spread over 6 months) to accomplish this, based on a 7x5 font... :) (multiple exposures per day)
...if you wanted to cheat, you could just record a whole year (say: photo every 5 minutes), and then choose the photos you wanted.
...otoh, doing it 100% in film would be true dedication! =)
