Mind boggling: http://theduereturn.com/
Yesterday, I walked through a REAL STEAMPUNK SHIP at the Center for Contemporary Arts in New Mexico!!! It was an experience of a lifetime. My written reaction can't do it justice, but if you check out the website, hopefully you'll grasp at least the scale of the project -- 50+ artists creating a interactive fictional environment.
And I thought that I was stoked getting Kenneth Oppel's autograph a few years ago ... What an AMAZING work of art in all senses of the word ... I was so awestruck, I didn't take hardly any pictures!!!
