I stopped by the Crystal Cathedral on Christmas day. Nicely decorated, though supposedly not as well as in yesteryear as they are going through some extreme financial problems (actually, baring a miracle, they will be the Catholic Cathedral in a few years).
It wasn't as crowded as I expected and there were many signs of financial stress around campus, but it's still an architectural marvel. I really like the contemporary styling, and find the inspirational messages, well, inspirational .
