The 4th Dimension Cement Wall Clock Links Time and Space.
This unique clock by Taiwan's 22designstudio is meant to link time and space, like that of the fourth dimension. The result is a modern looking wall clock made of cement whose form is much like that of a spiral staircase with the hands on the the top level. Light and shadow change with the movement of time evoking the name.
Available with blue or orange secondhand:
