Changing Pendulum

My eyes gradually searched the wall clock

Now the wall is complicated with an unknown piece 

Some one called this as the modern statue 

I never get why it's been hanged in the wall

Dad said: "Pendulum clock has been expired now"

"Your brother has fixed this piece of stuff and thrown the clock."

I find my brother's staring eyes and a deep silence at my dad's face.

He said "Pendulum is changing"
