The installation composed of 3 parts, one is layer by layer foundation, the second is 15 pillars which formed by continuous balls with relative proportion, the third is lateral net frames. Some of details are designed by mechanical limits.

Some commands of Form-Z 3D-software redeem the problem in force, such as animation toolbar. We completed this project successfully on account of many volunteers and Form-Z software .
