I'm really interested in Lipps' prop designs; they obviously work at high speeds. Has anyone read this book, or at least browsed through it? I'd buy it in a heartbeat, but the promotional web site has such bad sentence structure (structure in general, really). If the book is written the same way, I'm not sure I could extract useful info.
