It seems that lately, a lot of people have been using Virtual Earth to do some pretty amazing things. First there was this amazing DeepZoom thing and just recently, I located the blog belonging to the folks behind that project. Here, an older entry shows off a photo mosaic made with VirtualEarth tiles. John O’Brien created this image of the Sydney Opera House from maps.live.com using a bunch of tiles from the road and aerial views of the Live Maps image using images found in his PC’s cache. Then, using a tool called AndreaMosaic (it works on 64-bit, too!), he created the mosaic you see at the left of this post. If you want to make your own mosaics, too, there’s a tutorial here on how to use the AndreaMosaic software.
