Yesterday I happened to spot a local events calendar listing a Lego inventor's competition, sponsored by the Ann Arbor library. The projects were built on the inventors' own time, then dropped off for the event to a nearby hotel ballroom, and were on display for the public for a couple of hours in the evening. So we went. There were several tables with projects in all age groups, from preschool to adult, and we spent an enjoyable half hour or so walking from table to table.
Some of our favorites:
Lifecycle of a butterfly
Undersea adventure
apple car 
When we got home it was bedtime, but our own little inventor really really wanted to build. And what's the fun of a flexible schedule if you don't take advantage of it? We couldn't waste all that inspiration on sleep, so we let him build for a while. Then he built all through today, too. In fact, I have a feeling the floor in the front room will be covered in Legos for a while. And that's a beautiful thing.
