Chern and I have tried to construct this model for more than four years. I have basically made it today. But I may still need to clean all loose ends up. With a rough estimation, about 4500 beads and 100 fishing threads are used. Sixteen long threads (about 3.5 meter long for each strip) are used for making helical strips, and the remaining short threads are used to connect these strips. We can still see many threads in these photos. My wife made an interesting comment that this is really "千頭萬緒" (thousands of strands and loose ends, meaning very complicated) in a tradition chinese phrase.
The following two pictures are taken on my airport extreme.
