Peru photo albums

Note that I've commented many of the photos so you can tell what's going on.
Machu Picchu panorama
Inspired by this 1.5 gigapixel image I tried to play around with some stitched panoramas on my trip to Peru. You can click on the image to download the large (11 megabyte, 45 megapixel) file.

Altitude and GPS data from Peru
Further evidence that I am a pathological collector of gadgets; the chart below shows the altitude recorded by the GPS unit I got for Christmas. The unit, a Garmin Foretrex 101, is cheap (~$70), easy to pocket, and logs 10,000 data points that can be downloaded via serial cable; my only beef is that there is no native USB support. After downloading the datapoints with G7ToWin I use RoboGeo to sync the GPS tracklog with my photos and stamp GPS coordinates into each photo's EXIF headers.

Home from Peru
I'm back in one piece despite the airline's best attempts to delay me (32 hour trip home). I will try to put up some comments on the trip and more photos as time permits.
Woman posing for a photo in front of the incredible Inca masonry at Sacsaywaman (aka Sacsayhuaman). Rocks weighing 120+ tons were quarried 2km away and worked into irregular shapes with only a few millimeters of tolerance at each joint. The resulting stonework requires no mortar and fits snugly together to survive even powerful earthquakes.
