Okay, I keep referring to it as "Boom," but to be fair, Tim Marsden's contribution to The Wall is called "Is That All There Is?" Inspired by the Peggy Lee song of the same name, Marsden imagines what it would be like to experience a real-life (cartoon) explosion, complete with a big boom! and flying debris.

"Is That All There Is?" can be seen from Cal Anderson Park, and features real planks of wood painted to look like... cartoon planks of wood.
