This probably isn’t the kind of thing that mothers would encourage you to do, but some folks have decided to entertain themselves by coming up with some homemade hallucination goggles. These goggles are available in two flavors, which are the small swimming-goggle type model and the heavy-duty one that is made from welder’s goggles. Half ping-pong balls are used to diffuse the light from an RGB LED and the system is controlled by an Arduino with some buttons and 7-segment displays for a user interface. While we can’t say whether it’ll negatively affect your health in the long term, we can guess that it won’t benefit your health in any way. Still, bright colorful lights are generally welcome to brighten up your day (or night).
