Today I've been playing with materials to get a better understanding of how paraboloid structures work physically.
I started with origami paper (12"x12").
...moved on to screen origami (4'x4').
...and then modeled in kabob skewers (again 12"x12" square, the cheetah tape is for extra bling).
The peaks and valleys of the origami make it feel like it really wants to close up. The straight line sticks arranged as romboids is solid as a rock.
Next up, solid exterior frame and lace on the interior with wire.
