In the previous post, I shown two beautifully dual beaded models made by Chuang, which give an interesting application of beads with long aspect ratio. Due to the color of these beads, the contrast of these photos is not good. I made scanned images for these two new beaded models. The contrast seems to be better than the photo.
Previously, we have used this kind of beads to made a model of C60. The resulting structure is quite flexible and can be deformed easily under external stress. We claimed that beads with long aspect ratio is not suitable for constructing stable fullerenes. Now Chuang discovered that these beads are good for creating their dual structures. The rigidity of resulting structures are very large.
