While I have not taught from the text myself, I know of an informal geometry text that has been receiving attention by folks looking for a less traditional book:
Title: Discovering geometry : an inductive approach. Author: Michael Serra. Published: Berkeley, CA : Key Curriculum, c1992. Subjects: Geometry.
Students develop/discover theorems through their work on the activity sets, thereby "constructing" the Euclidean axiomatic system rather than having it given to them to commit to memory. The book is full of non-routine problems, practical applications, hands-on activities, and is replete with diagrams, illustrations and humorous story-problem situations. A considerable amount of attention is given to Escher's work throughout the book. (By the way, the book's author gave a major address at the NCTM Annual meeting in Indianapolis last year. Perhaps others heard him speak.)
