a book recommendation: Universal Principles of Design

I bring the following up as I was just on a thread covering the feelings of nausea some get when walking in malls or places that are very busy, so....

For those who build anything interactive in SL, stores, interfaces, etc, I have learned that a book i carry with me everywhere my day job goes has also been a valuable asset while designing in SL. I have no affiliation with the book--just wanted to share.

at work, as a GUI designer, i call this book my Bible, because i carry it like a preacher, and i quote from it, and then everyone shuts up . It covers 100 principles that can be invaluable while planning out your new store or building the next killer SL app, and written in an incredibly clear style.
