I keep seeing these linked around by curious folks, so I might as well just post them myself.
So early this year, TLG sent me an email asking me to sign a non-disclosure agreement with them. I obviously did, because duh, right? They then informed me that BIONICLE was coming back, and me and two other BZP staff members also under NDA have been working together on several projects (some still secret, some, like NYCC, no longer secret), but one of the things that happened were preview selections of parts sent to several of us (including a very small list of MOC-builders I was asked to choose). These are the two MOCs I built using them. I have several more in the works, but I ran out of time before NYCC, which was when the embargo on photos of these parts was lifted.
The silver huna is unrelated to this story, it's simply a non-production, prototype mask I received in a trade at BrickfairVA 2014, which was originally owned by a LEGO set designer.
