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. The Triple X series is 16-1/2 x 6". The length of the Triple X series allows for a greater range of mountains. Maybe you will get one mountain. Maybe you will get 20 mountains! Each turn will create a different sand picture. The Black Triple X is made of beech wood and finished with a black matte finishing. Prominent sand colors are black, ruby and gold. A stark, contrasting sandblend and a bold performer.
