In this file you will get a shader (material) made and rendered with cycles. didn't test this with other render engines or any other software.This shader doesn't Require any special or complex models, just a basic cube scale it so 2 dimensions are big enough (scale should be 1.00*1.00*1.00).Just download the .blend file and you are good to go.Colors are easily changed by the color ramp node, you can add as many colors as the color ramp node allows.please note that this file can be used with blender 2.xx
