The Modern Lines theme is characterized by black and white backgrounds and thin lines between photos. The cover can have a full bleed photo, a large photo with text, or three photos with text. There is the standard inside flap, three introduction pages, a maps page, and blank pages, along with one-, two-, three-, and four-photo layouts. The font Helvetica Neue is used throughout the book.
The Modern Lines theme offers only black or white for the backgrounds for the outside and adds the Photo Background option (formerly Palm Tree) to let you use any image you want for the background of the inside pages.

When you use the full photo bleed layout, iPhoto automatically fills the whole cover with it regardless of its original orientation:

If you'd rather use its original proportions, right-click the photo and choose "Fit Photo to Frame Size":

If you want text with a large photo, use the second layout, which changes slightly depending on the original orientation of your photo:

Finally, you can have three photos on the cover. The left box is always vertically oriented, regardless of the kind of photo you put there. The right two boxes are horizontally oriented. Be sure to move your photos around to fit:

The full bleed photo is as expected. The large photos vary according to their original orientation. Don't be fooled by the seemingly square image in the layout menu, it is a standard horizontal or vertical frame, with or without a caption.

You can choose a black background for one page and a white for the other for an interesting effect:

One striking characteristic of the Modern Lines layout is that two vertical photos are much larger than in other layout styles.

Two differently oriented photos have the standard layout:

With three photos, layouts are pretty standard:

With two vertical and one horizontal, changing the order of the photos changes the layout:

And with two horizontal and one vertical, again, the order of the photos determines the layout:
Note that there is one more combination for each of these last two examples, but they are very similar to what's shown.
The four-photo layout has rigid frames; the orientation of your photos is disregarded. There are three horizontal frames and one vertical. The latter is always in the lower-left corner.

Here's my description of the Modern Lines theme in iPhoto '08.
If you have any comments, questions, or suggestions, I'd love to hear them.
