I'm not sure if this is kosher or not, so if a moderator needs to remove it or anything, they certainly can...
With all of the Man of Steel and Superman LEGO sets that are going to be coming in May with the upcoming movie, there hasn't been any word of them releasing a Fortress of Solitude set. And I really, really want them to. So I designed a Fortress of Solitude using LEGO Digital Designer, and I've posted it on LEGO CUUSOO. The link is here: http://lego.cuusoo.com/ideas/view/31854
I tried to combine elements of the Superman movies/Smallville exterior with a comic book interior. So it has a crystalline kind of architecture, but it also has things like a trophy room and Krypton shrine, and a Kal-El Super Baby Rocket, and a Kryptonite vault.
Anyway. If you're interested check it out, if you want to, vote for it, share it with other nerds...stuff like that. If you have suggestions for how to make it better, let me know that too.
