An image of a tower in spain...very pretty. To see more images from the gallery, go here.
I found this really cool image that is created using the stereoscopy process, but it is a modern version of this process. I found it on wikimedia commons, which I have never heard of until I started looking for stereoscopes, but this particular page was cool. You are supposed to look at the image using 3D glasses, but it is pretty stellar without them.
