i keep forgetting to link this. right now, i can't remember how i stumbled across it, but i thought it was a really cool idea.

Collages in this project are made up of 64 pictures total. All 64 pictures must be original photographs, taken by the collage's creator. Each individual picture in the collage is 100 pixels wide by 75 pixels high, oriented horizontally. Pictures should be arranged in an eight picture by eight picture grid, forming the final 800 pixel wide by 600 pixel high collage.

i thought ... what could i take 64 pictures of? then it dawned on me that i already had 64 pictures of something. browse through the list. there are some beautiful collages there.
