The idea: To raise awareness of the urgency of blood donation, we created an hourglass with red-colored sand in it, which represents the blood. And we printed the profile of a man and the Red Cross on each side of the timer. So when you turn the hourglass up side down from time to time, you can easily find out the relationship between "you" and "the Red Cross", anytime one of them is running short of blood, the other side can help instantly.">
