Want to see how Las Vegas has grown from 1972 through 2010? NASA created this unique time-lapse video using photographs captured by Landsat satellites. From this perspective, it almost looks like humans are a mold spreading across the face of a fruit.

Portrait-a-day time-lapse videos show the passing of time in a pretty striking way, but so does this project by a guy named Sam Klemke. Every year since he was 20 years old in 1977, he has made a short video of himself announcing the passing of the year. Now, 35 years later, he has created a compilation of the videos that allows us to travel back with him through time — from the digital age to the age of recording video on film. Maybe it’ll inspire you to start a photo or video project that spans decades!
