In the 1700s, spherical glass bottles filled with water were used to focus candlelight for fine work such as lace making , surgery , http://www.explorato...er_sphere_lens/ Today, this technique of the sphere lens magnifier is still used , While searching the web, I came across on this Spanish site , This is the google translation , https://translate.go...t-text=&act=url http://www.nippon.com/es/views/b02306/ Liter of Light , Wiki , Is a global open source movement with the aim to provide an ecologically sustainable and free-of-cost source of interior light to rooms in simple dwellings with a thin roof. The device is simple: it is a transparent 1.5-2l plastic bottle, as typically used for carbonated drinks, filled with water plus a little bleach to inhibit algal growth, fitted through the roof of a house. During daytime the water inside the bottle refracts sunlight, delivering about as much light as a 40- to 60-watt to the interior. A properly installed solar bottle can last up to 5 years , https://www.google.b...ved=0CAgQ_AUoAQ
Well here we are! At the end of the process with just a day or two left to complete entries and submit photos!! This is my entry into the Jade Symposium Sculpture Category! Titled 'Hidden Within" to reflect both the colours of the Jade and how they change with applied light and the Bonsai etched onto the panels that disappear with applied light. The lighting is an LED light strip set on while light with a slow strobing effect to turn on and off. The fan dimensions are 8"L x 12"W x 1.5 millimetres thick - The light box makes it a bit bigger but not much. It also sits on approx a 45 deg angle for viewing. The light box is made from Yellow Cedar Burl. The Jade is from Dease Creek British Columbia. I particularly like this Jade because of all the "activity" & character within - however the black inclusions do cause a bit of heartache since they are very soft!! As always there are more images and video on my facebook page for those into that. Thanks Tom
