Triangle

How doe triangle communicates impermanence ? It suppose to be the most stable shape, but since I'm hanging it off the ground, the gravity becomes the permanent and everything else would risk falling!
I find beauty in the impermanence: Age, petals falling from the sky, water, dancing. I can't really duplicate nature, but it has its way to use same materials over and over again yet still be able to be unique in its nature's making. The triangular metal plates that I hung off the square net looks like a flock of bird, but it also looked like the shape of a fish. Swimming, flying, how free is that! but yet its tied to a string!
The installation goes from dense to less dense, leading the eyes to move around , and navigating the three-colored yarn with the metal plates that is hung off it.
I have a vision of Brenda's , the chair of department, who's a sculptor's work I saw over summer in the AVA gallery. I like to see how sculpture could work without heavy wood making, but simple strings and metal. Turns out that there are also lots to consider. the straightness of the triangle, the tensity of the string. How the knots are seen , or invisible, or just messy.
Argh, I am challenged but inspired and happy to constantly learning new things.

p.s. forgive this jibberish writing, I swear i will make sense of this later.
