A swinging pendulum is notoriously mesmerizing—that’s why hypnotists are always swinging pocket watches in front of someone’s eyes to put them under. But when you add an extra point of articulation, creating a double pendulum, the seemingly random and flailing motions that ensue go well beyond hypnotic.

In fact, if you need to get any actual work done today, then do everything you can to resist watching this video of Devin Montes’ Pendulus in action. Even though all you can see in this hour-long clip is the glowing end of the double pendulum and the trails it leaves behind, it’s almost impossible to break your gaze from the continuous swirling patterns this machine creates.
