This is Qlocktwo, the fourth dimension squared. A clock that tells time in words. It has a quadratic matrix of letters, where some of the letters are illuminated. The time is displayed as text in five minute intervals. If you need to have a more exact time, look in the corner at the illuminated dots. Qlocktwo has a brightness sensor; with its help the illuminating power of the letters is automatically adjusted.
Built in Light sensor for automatic adjustment to ambient light, DCF-77 time-signal receiver for to the second accurate time-telling without manual setting and its all handmade in Germany.
You can buy a program for the iPhone, so you can have the Qlocktwo as a wallpaper.
