When I entered their home, Alex, came running around the corner, cracker in mouth, "Cydney! Are marble tracks your favorite thing in the world?!" I told him I didn't know but if he showed me one it may become my favorite thing in the world. At the end of our shoot, Alex let me play with it a bit; a tower of plastic tracks, tubes and spinning wheels that marbles pass through from the top. Very cool, and quite possibly my new favorite thing.
