I'm a huge fan of the Alien series (especially 1 & 2)
So this just hit the web . . . Freak'n sweet Queen Alien Polystone Diorama from deshow!!!
Description: deshow Collectibles is proud to bring you the Queen Alien Diorama. Each diorama is cast in high-quality, heavyweight polystone, then hand-finished and hand-painted to deshow's exacting standards. Each piece is individually hand-numbered, and packaged in a durable foam interior and stunning printed box. The Queen Alien stands 16 inches high above a themed display base, ready to join your Alien collection.
This piece is $399.99 but looks like it's worth every penny to me
