I recently went to New Zealand, one of the coolest things I did while there was go up the
Sky Tower in Auckland. At first I thought it was going to be pretty lame, it's just another tall building, but the view up there is amazing. They have glass floors you can walk on, it took a lot of nerve, but eventually I was totally comfortable walking on them, check out the picture below. I took a lot of pictures up there, including nine I stitched into a panorama.
* To view the whole panorama at 100% you will need six 30" monitors.
