Get an expensive look in your bathroom for very little money. One way to cheat on the look of a large mirror is to use smaller glass tiles or sections, which, due to much easier production and shipping, will usually come at a fraction of the price.
Built and designed by Numen/For Use, N-Light Membrane is a giant cube with three out of the six surfaces made of flexible membrane (foil mirror) with an air tank and a compressor connected to it. The other three mirrors are semi transparent spy-glass. By inflating or deflating the air tank, the membrane turns convex or concave, deforming the reflections within.
