I thought of doing this, but thinking about my own 0.1 byte per hour connection I couldn't think of how to compress them enough (even JPG @ 400K each works out quite a bit). A rockhound, eh? My great-uncle was one of those! He had this massive & amazing collection of minerals and rocks and stone age arrowheads & stuff that I used to look at when I was a kid. Most of it's in the British Museum now, but it was well impressive!
