I find this extremely impressive. Especially how the museum tracks your 3DS and the app knows where you are. As someone who's currently taking an art course and planning on visiting the Louvre, I really can not resist to buy this. Fantastic job, Nintendo.
I don't have any /immediate/ plans to visit this fine establishment----but the virtual tour seems like a proper place-holder. It feels like a solid window to the Louvre, and not just the art, but the the architecture and ambiance that holds it. I'd love to learn a bit from this download.
