Google Mx, in cooperation with the Mexican National Institute of Archeology, has launched virtual tours of 30 famous ruins, soon to be 80. The ruins seem to lack documentation or explanation, but they may be of interest to prospective tourists who are trying to choose among various possible destinations. (If the images are unfocused initially, wiggle the cursor over the photo. It will eventually render sharply.)
