The LED wallpaper was designed by Ingo Maurer in partnership with Architects Paper in 2011 and is produced and distributed by Architects Paper.[17] Maurer's wallpaper presents itself as a large electronic circuit board printed on paper and can be affixed to the wall with normal wallpaper adhesive. The conducting paths printed on the matte non-woven substrate become part of the design, on top of which are distributed white, red and blue LEDs. The red and blue diodes form optical cuboids with the white lights loosely and irregularly spread around them.[18] The LEDs are controlled by a series of connection units which enables the individual regulation of the colours and the degrees of brightness of the LEDs.
