Hi, This panel about 2 meter high,is painted on that sheet with stencils and airbrush -- something that add a particular quality when light shine thru. Also all sheet work for 3dh,  Poly carbonate is a fascinating material but to use it you really have to understand it. --- taking profit from the way it is made and how light act within it really make a suggestion about Decor, something almost forgotten i today's architecture .

If you have access to a laser cutter you could etch dense lines which would distort light similar to polycarb panels.

Thanks guys!
