Tuomas Markunpoika - Refractile
'Refractile' is a creation of an enigma. We always get a surprising look on our faces when we see these kinds of phenomena. It's made by micro particles, however, it has a vast, transformational effect on its surroundings. By itself, no matter where it’s positioned, it creates a dramatic and pulse changing rhythm.
In 'Distant Lights', the image that the viewer sees is entirely based on his or her position, which is actively individually constructed by his or her own eyes. In 'Refractile,' the refractive image is already constructed: a collective, center-oriented image.
"Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light—when it passes from a fast medium to a slow medium—bends the light ray from the normal towards the boundary between the two media. The bending amount depends on the indices of refraction of the two media and is described quantitatively by Snell's Law. As the speed of light is reduced in the slower medium, the wavelength is shortened proportionately. The frequency is unchanged; it is a characteristic of the light source and is unaffected by medium changes."
The lighting structure uses a standard RGB LED strip mechanism to create refractive relations between the lights erupted from it. These are projected onto the material, a special polycarbonate film, in which the rays are scrambled over and over again. The rhythm is created by the polycarbonate's curving qualities and the different levels of mixture between the three separate basic light colors on the RGB LED strip. The use of polycarbonate material in this lighting structure also gives the lights erupting from it the capability to change the rhythm by itself, autonomously. The overall changing rhythm is achieved by using different velocity levels, colors and mixtures.
"Light can be described as a wave, and relative motion of the source of light waves leads to a corresponding Doppler effect for light. In this case, it is not the pitch, but the color (that is, the wavelength) that is shifted by the motion of the source. The wavelength shifts to larger values if the motion of the source is further away from the observer and to smaller values if the source motion is towards the observer. The shift to larger wavelengths by motion away from the observer is called a red shift by astronomers. A shift to shorter wavelengths caused by motion towards the observer is called a blue shift. The terminology is borrowed from the visible part of the spectrum where blue is towards the short wavelength end and red is towards the long wavelength end, but the Doppler Effect occurs for all wavelengths of light, not just the visible spectrum."
Another great factor that contributes to the change of rhythm is the relative position of 'Refractive Lights' in the desired space. Since it possesses physical qualities from the 'Doppler effect,’ when it is positioned in a small and dark space or close to walls, a more dramatic rhythm ambience is created (smaller values). In a large, illuminated space, we get a more graduated effect of rhythm (larger values).
