Designing a Gender Neutral Nursery?

My wife and I utilized the book "how to choose the sex of your baby" with 100% success- twice! We wanted to know our babies "she wee" or "he wee" status before giving birth, but many parents do not. I wanted to know mostly because the nursery design was important. Imagine that...HA! We signed and passed on the book to friends, who did the same. I have no idea where the book ended up. I'd be curious if it's still in circulation and what the success rate is? How about you? Did nursery design play a part in your wanting to know your babies gender?

A gender neutral, but not neutral colored room I designed for a client.  She has since had a boy.
