Jigsaw City - 4,619 Pieces

3D reconstruction of Dubrovnik, Croatia, containing 4,619 images and nearly 3.5 million 3D points. Very similair to Photosynth (which I have never been able to get to work properly) but obviously with much more data and complexity.
While the puzzle comparison is obvious, I think sewing memories into a quilt captures the process and product more accurately.
