This is so cool: in the early 1900s, a mechanical engineer named Louis Brennan invented a self-balancing train that ran on a single track. This video demonstrates how the train worked using a clever system of gyroscopes.
This is the Brennan Monorail, a train from the early 1900s that seemed to defy the laws of physics. Not only did it keep itself perfectly balanced on a single rail, but it mysteriously leaned into corners without any driver input.
It’s kind of incredible how well Brennan’s system worked. It’s ingenious. (via messy nessy)

As part of his Real Time series, artist Maarten Baas has created The People’s Clock, a timepiece that lives in Amsterdam’s Schiphol airport. To create the clock’s “workings”, Baas recorded more than 1000 volunteers moving as the clock’s hands over a 12-hour period. If you look carefully, you can see a single individual dressed in orange at the edge of the circle acting as the second hand:
Each of the installed clock’s faces is a looped video of that recording, synced to the current time. Here’s a quick behind-the-scenes video of how the clock was made:
