The art direction on the LittleBigPlanet site is fabulous and fun as hell. The rich flash experience takes the idea of the DIY game building experience and literally brings that to life.
There are corrugated box platforms held up by rope strung on on eyelets, hand drawn video controls, skateboards rolling to and fro as the platforms oscillate, and the little animated rag boy character flopping around as you navigate the space. And you know I love the folded graph paper backgrounds on the blueprint tool and sticker. Now I'm gushing. Love it. Can't wait to get it for my son this Christmas (don't tell).
