On another note;
My Cuusoo Flying Dutchman is nearing 1000 supporters, that means it might get an official LEGO review, support is more than welcome, I'd love to see what an official LEGO comment would say about the Flying Dutchman, perhaps it could provide an answer why it wasn't released in the first place.
That's an ingenious polar cruiser!, nice clean lines too. opening doors, usable crane, folding solar panels (hope they're high efficiency ones), and rotatable tracks. Sweet! And those seals are very clever!
Awesome moc, mate! I'm loving the snot ice, it compliments the water well. The jeep looks very realistic, and I know from experience that minifig scale cars are tricky. Also the treaded vehicle is great! It has many cool features that make it not only nice to look at, but lots of playability. The seals are something I haven't seen before, and they are clever. You and your sister make quite the team!
