My Great Grandpa Moore made a cradle. It has been passed down through the extended family and there is a list of "inhabitants" inscribed on the bottom. I, of course, am the most recent addition. He was a superb craftsman, as evidenced by the uniformity in shape and size of the balusters. I'm being serious.
On a less analytical note, I really dig that cradle. I have finally achieved a large enough wing-span to grab both sides at the same time. Score!
