Demolishing Curtis' Room

This mural shows the view from outside the old D building looking towards the old A building where Mr. Curtis' room was (this location is being made into a parking lot). The covered walkway connected to the C building and there was an amphitheatre.

The speech bubbles read: They need to mg for the 2*pi*sqrt(l/g) to end. I guess a wrecking ball didn't fit the budget.

mg is the force of gravity, and 2*pi*sqrt(l/g) is the period of a pendulum, which goes with the idea of needing a wrecking ball, which is a pendulum.
