Shinji-O has an incredible imagination for these things. I think the bottom one is my favorite. Like the previous builder, he has quite a range of creations here too. You'll have to check out the birckshelf page on this person.
No More Crowding the Other Blog with My LEGO Obsessions! This is a non-profit blog. If for some reason you don't want your awesome creations on this blog, I can take 'em off in a heart beat. Just leave a comment. Enjoi!
