A few books on The Church, it's members and it's purpose.

The Narnia exhibit at the Oregon Museum of Science and Industry (OMSI)

The other day when my family and I went to OMSI to see the Game On 2.0 exhibit, we also saw the Narnia exhibit. It was pretty cool. Jeremiah liked it so well that he went through it twice while we were there.
There wasn't a whole lot of interactive stuff, but there was a little. You could touch and feel the weight of a suit of chainmail. It was pretty cool. I'm glad I don't have to wear it as it was fairly heavy.  There was also a tower with the head, middle and legs of one of the creatures (a minotaur, maybe?) from the movie. The different sections spun around so you could change his legs, facial expression, etc.  Other than that it was mostly artifacts from the movies that were untouchable. Some of the artifacts had tv monitors next to them playing documentary clips to explain parts of the movie. There seemed to be a small emphasis on global warming. Thankfully it was a small enough emphasis that I could ignore it.
My favorite part of the exhibit was a small wardrobe that may have belonged to C. S. Lewis. It was set up with some old books inside, including first editions of the Lord of the Rings trilogy. Because I like old books, I found that part to be extra cool.
On the other hand, Judah (he's 7) got a little freaked out by a "lifesized" minotaur. Jeremiah and I thought he was pretty cool, but it was understandable that some would be nervous.
This exhibit did cost 2 dollars more than the regular admission, but if you liked the movies 2 dollars isn't that much. It was neat to see some artifacts and to watch some of the video commentaries. There were also maps and clothes displayed  and one more interactive thing that I forgot about. It was a fairly large map with lights on some of the locations so you could see where different places are in relation to each other. Narnia is a larger piece of real estate than I imagined.
