It’s such a brilliant idea I can’t believe it hasn’t been done yet. I found this while browsing for Beast photos.
Quote from the Campaign page:
"Hello Marvel comics! There is a fan campaign to create a Lego X-Mansion (http://lego.cuusoo.com/ideas/view/53799 ). It needs only 10,000 votes for Lego to review it.
We realize that getting a set produced is a long shot, but please consider sharing this project with X-men fans via your facebook and twitter feeds to help us get this project to the review phase and celebrate our love of the X-Men.”
