Paris 26 Gigapixels took 2,346 pictures of Paris from atop the tower of Saint Sulpice and stitched them together into a 354,159 x 75,570 pixel panorama of the city.  Pan and zoom at your leisure.

Like in Google Earth, the zoom feature is blurry at first.  Give it a second to crisp up and you’ll be absolutely astonished at how much detail is there.  Zoom to the absolute far reaches of the image and you’ll still be able to see individual people walking around.

Special challenge: find the bright green “3:14π” sign and identify what the adjacent shop most likely sells.
