Agree with you, sir. I'm not the target market, but I'm not entirely sure how this application differentiates itself against the bigger names in the space (namely Carbonmade). I'd be interested to hear what the OP says.
With Sliding Boxes, my goal is to offer artists a more beautiful and customizable canvas for their work. Boxes on the portfolio's front page slide to reveal other artwork. And because it's built as a one page application, page transitions are sublime: http://lucalagreca.slidingboxes.com/
