, but here's a few pics that I snapped with my phone of the newly built arc reactor for the MkVI/VII from the paused Bluray. The first three pics show the arc reactor right after Stark places the new element in, as the reactor is "accepting" the element.
The last two pics are as Stark is installing the new reactor into his chest for the first time (as the toxins reverse). One thing that I find interesting is how different the reactor looks between the two sets of images. Production inconsistency? Something else going on with the operation of the reactor that wasn't shown on camera? Dunno. But, in the end, I based my build on the latter pic, as trying to get a convincing blue triangle to light up was causing me some strain. :cry
Here's mine...
