Intentional light variations are applied for warning, signalling (e.g. traffic-light signalling, flashing aviation light signals), entertainment (like stage lighting) with the purpose that flicker is perceived by people. Generally, the light output of lighting equipment may also have residual unintentional light level modulations due to the ...
Temporal light artefacts (TLAs) are undesired effects in the visual perception of a human observer induced by temporal light modulations. Two well-known examples of such unwanted effects are flicker and stroboscopic effect. Flicker is a directly visible light modulation at relatively low frequencies (< 80 Hz) and small intensity modulation levels.
Flickering animation of a scintillating scotoma, where the scintillations were of a zigzag pattern starting in the center of vision, surrounded by a somewhat larger scotoma area with distortion of shapes but otherwise melting into the background similarly to the physiological blind spot
In its original form, a Dreamachine is a work of light art made from a cylinder with regularly spaced shapes cut out of its sides. The cylinder is then placed on a record turntable and rotated, depending on the scale, at either 78 or 45 revolutions per minute. A light bulb is suspended in the center of the cylinder with the rotation speed ...
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.

The work exploits the existing light fittings of the gallery space, modifying the lights using an electrical timer. [ 7 ] [ 6 ] Lights switching on and off form a recurring motif in Creed's works, including Work No. 127: the lights going on and off (1995) [ 8 ] and Work No. 254: The lights in a building going on and off (2000), [ 9 ] in which ...
