With Google Earth, you can tell how God feels about the Earth. I often used Google Earth to roll the Earth at my disposal on the screen. Nature and people painted many pictures on the surface of the earth. The sight of famous buildings and places from above was even more monotonous than I thought. The golf course in Yongin looked like a cluster of worms from the top, and there were many unthinkable forms of architecture in Shanghai. I drew it in the form of what I thought was beautiful. When placing the form on A0-size paper, numbers were assigned according to the form of the line from No. 1 to 100, with irregular curves in the beginning, straight curves in the middle and straight in the latter. A total of 100 shapes of 47 cities have been drawn, and the numbers on the sides of the form and the index on the file cover can be adjusted to identify and appreciate which area. You can feel the thick surface by printing silk screens on thin, large sheets of paper and touching the lines with your hands. I put it near my desk and often opened the poster, and made a cover using the sleek file paper.
