It's finished! I've just finished the book, I'm uploading it to Apple's MobileMe cloud drive so my publisher can download a 114MB compressed archive containing: a preface, table of contents, 14 chapters, further reading, two appendices, all the images in the highest resolution possible (with their copyright status) and some ideas for the book cover. To be honest I don't want to let it go. I know I could improve it and there'll still be a few errors in it.
Now it's over to the team at Springer.
