Motorized Zen gardens are nothing new. We have covered a bunch of them that create patterns in the sand slowly and help take your mind off things. You can always build your own with a 3D printer and a little bit knowledge of electronics. This 3D Printed Motorized Zen Garden by BeAlphaPrints is made with PLA plastic. It has a silent motor not to take away from the experience.
You can customize primary or sand color. This sand garden measures 2 x 8″.
