the circulating hourglass light by juwon cha from korea

borrow time from nature

a new concept of hourglass
this clock borrows(not use) sand from beach

everytime is a part of life in weal and woe.
we never do not get these lost times back.
how do people use this valuable time?

time is just flow murmuringly,
but people is locked up in time by themselves

people need not a artificial time but a natural time

this clock gives you the time of you
