Water forms part of everyone’s childhood memory, whether it's swimming in the ocean, paddling in the pool, dipping in the lake or horsing around with a hosepipe. Water can take any shape and reacts immediately to any external force; perhaps the unpredictable nature of water is what intrigues people to play with it, what causes children to spend an afternoon of excitement under its spell. Truly, in water, nature has designed an incomparably ingenious medium of interaction. Everything and everyone of us is interconnected in a myriad of ways: people with other people and all of us with the environment. Life is comparable to an expanding ripple across the water. Everything we do and think affects the people in our lives and their reactions in turn affect others. The choices we make have far-reaching consequences. Each of us carries the capacity to change the world in small ways for better or worse. If nothing we do matters, then all that matters is what we do. 'Wavelet' is created to demonstrate this phenomenon. It creates an unforgettable experience and turns audiences into participants and co-creators. 'Wavelet' is an interactive light installation created by Geeksart New Media Art Group. It uses the changing light to mimic the flowing water. 'Wavelet' is composed of 1,300 light-responsive light bulbs. Each light bulb is designed in an arc shape, which gives the light wave a distinct direction.
