Designing across the fold, specifically no. 3 is cool. But, it might be difficult for tablet format. --- Frankie - I love this layout, its a great, detailed black and white set up without loosing the texture of the content!
I think these layouts are a great example of how to make pages graphic heavy, and yet integrate text very well. However, where the most intense graphic elements are, my eye usually goes the wrong way across the page (i. right to left)
