California Academy of Sciences, Sneak Preview

Just got back from a sneak preview of the new California Academy of Sciences. Amazing. I was really looking forward to seeing the Living Roof:

I was wondering how long it would last, considering the roots would be digging in. The roof is actively managed to keep out weeds and plants with deep root systems (i.e. a pine tree sapling was found and removed).

The aquarium is awesome. Believe it or not, I've never been to the Monterey Bay Aquarium. After this, I need to go.

I can't ever remember going to a planetarium, so I can't make a comparison, but I could spend hours in there. The show I saw had the planet Earth, with us rotating around it, with the constellations marked out and the Sun . It is the largest, all-digital, planetarium in the United States (in the world?).
