The exhibit touted the navigator as a commercially available product. There were no Barbie dolls or GI Joe action figures. I guess I don't understand the question. I also took a turn piloting the rover and it was great. Although the Tech is smaller and cleaner, and more of the exhibits work, the Exploratorium has the touchy-feely thing down.
Every exhibit there is meant to be touched, prodded, or explored.
The exhibit of photographic copies of impressionist art wasted valuable space. The real Monets had been on exhibit in San Francisco earlier this year. He really liked things he could touch, move, or control. At the Tech museum, a large mousetrap sculpture that uses billiard balls on raceways is where older kids from around the museum gathered to discuss what was cool. I listened in.
