2018年12月，在历时8天建造后，一组500平米装配式钢构空间装置在上海当代艺术馆（PSA）前广场呈现。作品由大象设计联合同济大学、东南大学、中国美院学生共同完成。整组空间由“剧场”、“展场”、“趣场”组成，融合了社区活动、艺术表演、亲子游戏等功能，吸引人们参与，在冬日中激发出街区的热情活力。从空中望去，它仿佛一片洁白轻盈的“三角之洲”，成为这个城市江边的“引力场”。

In December 2018, a set of fabricated steel installations of 500 square meters were showcased at the front square of the Power Station of Art (PSA) in Shanghai. The creation was completed by GOA in collaboration with students from Tongji University, Southeast University and China Academy of Art. Divided into three parts, namely, “Theatre”, “Exhibition” and “Leisure”, the whole set of spatial structures also present community activities, artistic performances and parent-child games to attract wide participation and spice up the vim and vigor of the blocks in winter. When overlooked from far above, the fascinating Gravitational Field by the riverside looks exactly like a white and light-weight delta.

上海当代艺术馆是上海重要的文化地标，其西侧入口广场在平日里却是失落的一角——它的地下是社会停车场，地上有一片120米长，30米宽的区域平素少有人迹。西侧接壤的世博最佳实践园区是一个正常经营的办公园区，目前也在不断地发展丰富业态的过程中。夜间的广场上会有些许人员活动，主要是散步或运动的居民。我们希望通过多层次而有场所感的空间，将人的活动合理安排。

The Power Station of Art (PSA) is an important cultural landmark in Shanghai. The square at its western entrance is often an unfrequented corner. Under its ground there is a rarely-visited parking lot that is 120 meters long and 30 meters wide. The Urban Best Practice Area (UBPA) that borders on the west side is an office area in operation, and is still evolving. The square at night sees some visitors, mainly residents going for a walk or doing some sports. We hope to reasonably arrange human activities through spaces of distinctive functions.

引力场活动的20天里，每天9点至17点之间由一位艺术家在展场中展出作品，称之为“闪电展”。而17点之后，展场内空无一物。由此，在满足展览需要的条件之上，年轻的设计师们设定了一个“无展之展”的情境：让PSA的大烟囱成为展场空间“自带”的展品！半透明的阳光角吸引着人们由水平延展的低矮入口弯腰进入金字塔式的展场空间，而一个巨大的三角形高窗朝向PSA，精确框景了高大的烟囱。此时，展场自身也已成为一个取景器式的装置作品。
