If you were to watch Matt and Ben install a mobile or ceiling sculpture, you might get kinda bored. It's usually several hours of very tedious work.
But in this time lapse video, you can watch 13 hours of work installing a ceiling sculpture in just 25 seconds!
As you can see, there's a whole lot of up and down to hang all those strands properly. Also, pay attention to how the lighting and shadows change as the day progresses. So cool.
