(...) I don't have the parts to try this out, so my suggestion may be highly disposable. How about making each black triangle a 4/3/4? By this I mean: each black/white join would be 4/4, and each black/black join would be 4/3. The pentagon wouldn't (...) (21 years ago, 16-Sep-03, to lugnet.build.sculpture, FTX)

(...) Originally I thought of using 2x1 plates with one stud to get a 1/2 stud value, but your 6/5/5 idea is probably (much) better. The precise value is 6/5.1/5.1 so here the pentagons will be taut and flat. There is probably enough slack in the (...) (21 years ago, 15-Sep-03, to lugnet.build.sculpture, FTX)

If you're making something *really* large, you might have to brace each triangle with a second set of hinges on the corners. Don't know how well it shows (...)

(...) Yup, I realize that now. Holding the big ball in your hands can really make those ideas clear! The problem is, how to do it within the limits of the "Lego System"? I want to experiment with other triangle sizes, and see what happens and what (...) (21 years ago, 15-Sep-03, to lugnet.build.sculpture, FTX)
