Leaning and branching obelisk in the form of a tetrahelix.
Space frame trellis with a double cantilever, analogous to the branching of a tree.
very cool John,
I started making a non-stretched tetrahelix from 40″ long electrical conduit sticks, so far it’s 25ft long. I welded steel points at each end 1st, then welded the sticks together, but I’d really like to make a large ‘stretched’ tetrahelix. How do you figgure the lengths of the sticks?
