The book is vaguely related to PhotoReading. I'm not sure if there is an English version of it, but if you like optical illusions, it's only 1200¥ or so. It also includes stereograms, which some people find good for practicing PhotoFocus, and others (like me) just find generally annoying.
I'll see if I can find it next time I'm at Mitsua.
If you would like to have more information on this text, you can read the [url="http://babelfish.altavista.com/babelfish/urltrurl?lp=ja_en&url=http%3A%2F%2Fwww.amazon.co.jp%2Fexec%2Fobidos%2Ftg%2Fdetail%2F-%2Fbooks%2F4901782169%2Freviews%2Fref%3Dcm_rev_m ore_2%2F"]editor review[/URL]. This is a machine-translated page, of course, so it'll have a very "all your base" quality. Enjoy.
