This repository is most of p1k3.com.
archives/ contains the actual entries. Layout is generally something like:
2009/ `-1/ |+27/ |+3/ |-cart_small.jpg `-index
2009 is a year, 1 is the month of January, and everything below that level is a day. Some days are simple blobs of markup, others are directories which may contain an index file, binaries like images, and one or more sub-entries.
