This impossible and intricate triangle occupied me for about three hrs, but now that I understand how to do it I am sure it can take much much less.
It would be interesting to try it with different colours also, as the one that did Gwen Fisher.
Again, I tried to reproduce one of Gwen Fisher's creation (from the Bead infinitum site) and as she writes, she got inspiration to do this triangle from Roger Penrose's impossible triangle, who also inspired the genius artist M.C. Escher to incorporate it into his famous lithograph "Waterfall" (1961) after reading Penrose's article (see the way leading to the waterfall in Escher's litograph - which are in fact, two connected impossible triangles)
This intricate infinity also reminds me of Escher extraordinary and impossible beigels.
I wasn't sure I connected it properly since I knew from Gwen's triangles that it might be tricky, but when I saw that all the AB 15/0 greenish-golden beads became all only one edge - I could relax :-)
