the world's longest exposure

david has been really into stumbleupon lately so while i'm attempting to write one my tutorial papers he sends me links like thisthisthis and photos sometimes like this:

my favorite link that he's sent so far has been this:

the world's longest exposure photo,
taken for 6 months.
it was taken from dec 19, 2007 to june 21, 2008
from the winter to summer solstices
and the lines mark the sun's travel
it's so beautiful.
you can read the story behind it here
