Another fun book to read on the subject of dimensions (and I
believe this was mentioned in Rucker's book too) is "Flatland" by Edwin A.
Abbott (check the spelling of the last name). It doesn't deal directly
with the fourth dimension, but presents a very fun and lively debate on
the problems and wonders of discovering higher dimensions, through the
eyes of a character named a^2.
