The Qlock by Biegert & Funk forms a perfect square and seems to hover freely at the wall. A matrix with symmetrically arranged characters constitutes another square in the interior. Some of these characters shine in pure white to form words that describe time. LED lighting  and an ambient light sensor provides comfotable light levels. All colors are each available in german, english, french, italian, dutch, russian, danish, norwegian, swedish, arabic, swiss german, portuguese, catalan and spanish.
