In and out

We have been noticing that Stanley is more and more interested in takin objects out of a container and then putting them back in. He will sit for minutes (this is like several hours to him) and put blocks in and out of his wooden container.

Today I saw him take this interest to a whole new level. While he was playing by himself in the living room (I was trying to put dinner together) he spent the whole time shuttling his various toys over to the gate separating the living room from the kitchen and then tossing the toys over the side of the gate and out of the living room. Here is a picture of his handy work. I'm curious how far he takes this.
