Chrome Pit and Pendulum
Let simple physics relax your mind as you watch transfixed as this cool new Chrome Pit and Pendulum goes through its motions. Just give the free swinging pendulum weight a gentle push and let gravity and momentum determine the path as it swings slowly back and forth carving elliptical loops and whorls into the sand down in the pit below. Different start angles create different patterns, so this ought to keep your mind occupied as you waste away another boring day at the office. Of course, it's also a great decorative addition to the home as well.
