As production nears, those with access to the closed Helix website have been required to sign an NDA, or risk being locked out of the web site. There is at least one case where everything backers-only has been copied to a forum somewhere in SEA, and of course myself, having posted some pics in this thread too (although I have been careful not to divulge sensitive issues). So I can only give news of a more general kind but no pics which aren't available at the public section of the Helix site.

We have also been given the promise of getting regular updates every 2nd Friday, as pics or posts in the "activity stream", which is a bit like a visual element blog.
