The Light Painter

"Are not gross bodies and light convertible into one another; and may not bodies receive much of their activity from the particles of light which enter into their composition? The changing of bodies into light, and light into bodies, is very conformable to the course of Nature, which seems delighted with transmutations." - Isaac Newton

Standing by the words of Newton, and the impartial sustenance that light provides to aesthetic, displeasure and everything in the visual order, The Light Painter invites the public to create their own art with light and its constituent colours as their medium. It was a featured installation presented at the Jawaharlal Nehru Planetarium Bangalore, during the Kalpaneya Yatre 2010, commemorating the International Year of Astronomy. The Exhibition ran from November 26th 2010 to December 5th 2010 with Near 8000 Visitors Daily.

The Light Painter demonstrated the ability of light and its divergent colours, as forms of energy, to be transmuted into other forms of energy and back into light through people’s creativity. A projection of light in its constituent colours, a colour picker in the form of a freely rotating wheel housing an RGB Sensor, an IR LED Pen, and a hacked WiiMote to pick up the strokes made by people formed the Light Painter.

The Light Painter concept was further prototyped as an educational aid, which created an interactive surface out of any wall and allowed multimedia content to be manipulated with the pen.
