Vinal tubing joint construction.
A 3 spar, 6 spar, 9 spar and a big 12 spar joint (largest in the kite).
Not shown is a 6 spar corner joint, (looks a bit like the 9 spar joint).

Tetrahedral flying well in late afternoon, after the wind picked up.
Top right and bottom left cell broken, causing a bit of a lean,
and yet it continues to fly, rock steady in the sky with good lift.
