Have you seen that it is a clock?
The clock has three layers of rolling pointer on its base.The largest pointer represents hour,the middle one represents minute hand,and the smallest one is second hand.The pointer that points the slot is the current reading.
When at r 12 o'clock at noon or 0 o'clock at wee hours,it just reverts to a cube.So ox.
Such a bovine clock only sells at USD12.Furthermore,it's made in China.
