Wrist Watch which can be Viewed from Either Side

 Clock, which invented the designer Matej Korytar, the author calls «4D-clock", but perhaps this too loudly, though the idea of the device is interesting. In order to find the time to «4D-hours, you do not need to turn his hand - device itself adjusted to suit your needs: time can be displayed on any of the four faces of the transparent display, while the position of digits is determined by gravity (probably thanks to the accelerometer) and slope the user's head. Configure the clock should be using the two buttons on either side of the display. Until «4D-hours" - just a concept, but very interesting.
