The view from near Grettislaug, a hot spring in northern Iceland, over three summers. The island of Drangey is visible in the waters of Skagafjörður.
I'm amazed at what Photosynth will take. In 2008 I made a couple attempts at making a 360-degree panorama, but I was very sloppy about exposure matching and staying level, and the low sun didn't help. Those photos form the backbone of this synth, supplemented by photos from several days in 2005, 2007, and 2008. All three years are represented in the largest synth! The "geography" in that synth isn't perfect, but considering it's auto-generated, I'm still impressed.
