Klaus Bosch"s Rainbow Vision Sand Pictures are interactive, ever-changing, mesmerizing and versatile art pieces. Put them on your desk and watch them evolve with a new creation with each turn. Put our "movies" on the wall and enjoy the added dimension of the image to enhance the performance of the sand. We offer a range of Sand Pictures for every budget and every person. We have found men like them as much as women. We have found children like them as much as grandparents. People from the mountains are as fascinated by them as are people who live by the ocean. We have items for less than $25 and more than $2,000. Truly, there is a Rainbow Vision Sand Picture for everyone (and in many cases, more than one!) Klaus makes the Rainbow Vision Sand Pictures in his studio in Lustenau, Austria. Each piece is handcrafted with love and attention to detail. He uses a complex, yet beautiful blend of sand which is carefully selected for each frame color and / or movie image. The soapy water provides the medium for the sand to fall, but the real secret is the air. It is the air barrier that separates the sand from the water. That is it: air, sand and water! The sand will search to find the weakest link in the air-bubble barrier. The flow of sand between the bubbles will create dunes, mountains, and valleys. A slower flow of sand will result in a delicate trickle of sand making more dramatic peaks and valleys. A faster flow of sand will make dune shapes. Best of all is you control the amount of air in each sand picture so you can make the sand fall as fast or as slow as you want. The Sand Pictures are educational for children while soothing and relaxing for adults. There are many sizes and shapes to choose from. There really is something for everyone! A sandpicture will do several times a day what mother earth takes millions of years to accomplish.
