Thought some would enjoy... the most recent entrant is a 6" Discovery from Shapeways. Other treats are Capt. Cardboard pod, Twinch Squad figure from Spain, monolith award replica. And, of course, the fully detailed helmet! Enjoy.
Thanks for the kind words... here is the original link to the discussion on this site that led to me finding Predictamike who created the helmet for me. He was absolutely professional and great to work with, and his work is truly "museum quality". We exchanged some e-mails a year or so ago, and I know that at that time he was working on a full suit.
I'm also including another link below that describes and shows what I believe to be the same helmet. I have not had any dealings with this organization, so cannot endorse their product (although it appears to be the same).
