In the upper part of the design, a swinging joint is situated, allowing for smooth movement of the pendulum. Three steel supporters, connected to the base, are used to keep it intact. The screen is made from photosensitive material. In the lowest part of the pendulum an UV laser is attached, as well as a weight, to give the pendulum enough inertia to swing continually.<\/p>\n","protected":false},"excerpt":{"rendered":"
