Sandglass time / alarm

There are two major display modes of alarm: analog or digital. Sometimes you will forget whether you’d set time or not. This time sandglass is design to solve this problem. You can tell the situation of the alarm by the location of the box.

Feature
Transform the image of sand fall down in the sandglass to time flow in this design. Look at it; you’ll know whether you have turned on the alarm or not. Lift the box to start the alarm and it will fall down slowly according to the time you set. Longer time you set and more slow it falls. When the box on the machine fall down to the bottom, the alarm will glow and make sounds to remind you.
