Tetsuo Kondo Architects of Tokyo have designed a mirror that reflects a clear image when viewed straight-on but appears cloudy from the side.
A special film laid over the glass creates this effect, while the frame is covered in embossed paper.
Here's a little information from Tetsuo Kondo:
Special film is applied to the surface of this full-length mirror, which reflects a clear image at its center, when looked at directly.
Functional in essence, the piece also maintains the aura of a sculpture, softly shining when seen from an oblique angle.
Depending on the beholder’s viewing angle and distance, the mirror’s appearance transforms.
The frame is finished with subtly embossed paper, revealing itself on close inspection.
