You asked for it: some pictures of Machu Picchu

The Incans had abstract representative art. Take a look. When it was first discovered, people thought this thing was a sundial. But considering the uneven surfaces and angles, it doesn't work as one -- besides, if these people wanted to make straight lines, they certainly could. After "modern art" was invented, researchers started to think that this object was a sort of abstract totem that allowed Incans to offer sacrifices of chicha or whatever to the sacred mountains. Apparently there's one just like it on top of Huayna Picchu, but we couldn't climb the mountain because it was wet and dangerous.

The system of fountains at Machu Picchu is incredible. A series of stone canals channels water from a spring down to the first fountain, located within the royal residence. As you can see, the engineering is pretty good -- the water drains to a corner of the basin and moves down the hill a ways to the next fountain. There are 16 fountains in all, and 500 years later, the water still flows through them with no interruption.
