I also have a serious thing for cross-sections & cutaways. It's so much fun to get to peek inside something & see how it all works. Peacay of Bibliodyssey has posted some beauties & I was filled with absolute giddy glee when I first saw the "Let me tell you about my boat" scene from The Life Aquatic with Steve Zissou. {Sorry this is such a lo-res copy-- if you know of a better link please let me know.}
And have you seen this wonderful animated version of "Man as Industrial Palace" by Fritz Kahn?
Oh yes, back to the curiotype. It's Photoshop with text from Gray's Introduction to Structural & Systemic Botany, 1876
