Ambigrams Revealed Sample Spreads

Here are a few sample spreads from the upcoming book Ambigrams Revealed. While the book isn't due until the end of the year, I'm almost done with the design, despite the fact that I'm using lorem ipsum and my own work as placeholders. Take a look, and any comments/feedback is appreciated, no matter how critical it is: I won't get offended…not much anyways. ;)
