Where does it come from?

Riley had another creative burst in the middle of his bedroom. I think I can let the pictures speak for themselves but what you need to remember it that each "installation" is musically accompanied. This one featured "Fireflies" by Owl City. There was also a band playing to an audience, a cat on a trapeze and a baseball player swinging a bat. Enjoy.

To answer the question posed by the title of this post - all over the house, garage, basement and the neighbors houses if they aren't careful.
