Earlier this year, UT Austin grad student Matthew Goodman set up a Canon DSLR on Razorback mountain, which overlooks the desert where Burning Man was held. Over the next two months, the camera snapped a photograph every 10 minutes, resulting in roughly 8,000 12-megapixel photographs. Goodman then used the images to create this impressive time-lapse video showing 5 weeks of Burning Man in just 5 minutes. Every second shows 3 hours, so a full day passes every 8 seconds.
If you’re interested in learning more about how it was done (including how they managed to keep the camera powered), Goodman has an in-depth writeup on his blog.
