Yeah, all of them seem really... bright. I'm going to guess some psi involvement in these pictures, maybe they're sigils or mated with constructs?
Either way that was interesting.
No, there is no any sigils or constructs from any of the picture given above.
There is only a pattern---mathematics, that activate or trigger certain light codes in your DNA blueprint(Don't get it wrong with constructs, it's not constructs you known by means of psionics).
