The Newest Marble Run

I have a bit of an obsession/fascination with marble runs.  I'm not sure what it is about them, but I think they are great fun.  Some of my finds have been more fun than others - my newest one is a white board magnetic set of marble run pieces, and it has been quite enjoyable.  I find myself wishing my white board was twice as big (which would be quite the feat since it is already 4 feet x6 feet!), and that I had three sets of the marble run pieces.... but as I know I'm a creature of excess I'm going to just go with what we have.  We're having fun and it's all good.  :)
