A light bulb is suspended in the center of the cylinder with the rotation speed making light emanate from the holes at a consistently pulsating frequency range of 8–13 flickers per second. It is meant to be looked at through closed eyelids, upon which moving yantra -like mandala visual patterns emerge, and an alpha wave mental state is induced.
A light and sound machine with headphones and strobe light goggles. A mind machine (aka brain machine or light and sound machine) uses pulsing rhythmic sound, flashing light, or a combination of these. Mind machines can induce deep states of relaxation [1] or concentration. [2]

It is an exact counterpart of our physical ...
Green goo oozing from electrical sockets and flickering lights might not be a sign your house is haunted this Halloween - but rather a call is needed for an electrician, according to a campaign group.
In visual perception, flicker is a human-visible change in luminance of an illuminated surface or light source which can be due to fluctuations of the light source itself, or due to external causes such as due to rapid fluctuations in the voltage of the power supply (power-line flicker) or incompatibility with an external dimmer.
Flameless candles display flickering light, imitating that of actual flames. As a decorative element, the design of a flameless candle is relatively versatile. The body or "housing" of the device is commonly cylindrical, containing a battery pack and an often flame-shaped LED lamp atop the candle. Many manufactures use LED lights with an ...
The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science , more specifically in the psychophysics of visual perception .
