"The Field of Hope" used a matrix of over 30,000 artificial plants with LED tips to echo the EXPO's theme - agriculture. From outside, the plants of uniform height below the eye level expanded all the way into the pavilion, allowing visitors to see through the pavilion from outside. Visitors went gradually down into the field along a slope. While they moved forward, the change of height would make them feel that the plants were growing with the passing of the seasons.
