I found these interesting curtains on . Deluge 3D Curtains by gives one access to an unusual 3D panorama. Here is more from the designers:
For an apartment at the seaside of Knokke, Belgium, we were asked to design curtains for the living and bedrooms. The living room has a view of the sea, and for this we created 3 layers of ‘voile’ curtains, working as a 3D panorama, every layer having different boats in depth, drawn by Eric Klarenbeek. The backside view of he apartment is poor due to the facing housing block. Therefore we created two layers of curtains. One thick light absorbing curtain, with the dutch dunes, and one layer of a thin voile, with plants and animals. All photographed by Eric Klarenbeek, on the island Texel in the Netherlands. Especially at night it’s difficult to distinguish whether its real or virtual, giving you a feeling of being able to step out of your door, right in the fields.
