Mobily’s website oddly mixes main navigation (home, about me, contact) with portfolio’s pagination (previous/next).

That’s kind a strange and incorrect from a stricly functionalistic standpoint, but, being this website an one-page website, rather easy to navigate, I don’t think it’s a big deal if the designer wanted to shuffle things a little . Aside form that, the ajax horizontal sliding it’s quite enjoyable (if you don’t click too fast, otherwise it will make you feel dizzy).
