Marble Run - The Next Generation

Given how much fun the little folk got out of my father's marble run we had to buy one for use at home.

We kept two sick kids very happy, and ultimately hyper, tonight by building this run. For the 1st time the little boy (not yet 21 months) figured out what he was supposed to do with this one. He figured dad's out months ago as can be seen from the picture linked above.
