I recently read a story about a wedding gift that gave a distance to a destination, and would not open until the destination was reached. It is based upon a mix of Arduino, a gps sensor, and good old inventiveness baked with art and engineering, and was finally frosted with love and emotion for friends. What started out as a private wedding gift, and eventually brought much of the world into it’s story, is in 4 parts, took a year to accomplish, and is a must read.
